I posted this on Facebook and got overwhelming support, many members may have seen this car before, but for those who have recently joined, here's another couple of photo's.
Jim Clark's Lotus 33, US Grand Prix 1965.
Gears are Ranch Designs, Front wheels are BWA 13" mediums, rears are Old Pattos, machined, Drivers head is PSK, body is the fabulous Immense Miniatures full length, tyres are MRRC fronts, and AB slotsport Urethane rears. The hidden stuff is a Mk 3 Beardog Chassis (designed specifically for 65 F-1 cars, with a Mashima motor. Even a Mabuchi 030 can is too big for this car. It should go pretty well, it's the same set-up as the Eagle Climax.

But David that's the secret. twist my arm and I'll tell all.......
OK OK here goes.....yes you are correct it is a very heavily reworked Monogram Lotus shell.
This car has been an ongoing build for at least 5 years. The first car, (pictured below) was going to be a Beardog Racing production item. Inspired by a Monogram based Lotus that I saw Al Penrose build, or should I say start to build.
Al split a Monogram Lotus 33 down the center and narrowed it by 2-3 mm. OK I thought that makes sense, so I did the same. I cut out the cockpit, and modified the rear of the body to the correct swoopy lines of a late model 33. I built all the accessories: driver, transmission, injectors, wheel inserts etc and sent it off to Al Penrose because he said he'd mould it for me.
Well it was in Al's bat-cave for quite some time, and I inquired apon progress. Al said in his opinion the Lotus was still too big, and he had reduced the "deck height" considerably, and he was working on cleaning it up.
That's where all progress stopped and it still lives in Al's bat-cave #2, and is awaiting the magic hands of it's new master....Al.
Rat's I thought, how to solve the problem? So I started anew, but this time I did my homework and got the correct dimensions for the Monocoque tub. Based on these dimensions I compared them to another Monogram shell I had been graciously given by Mr Mark Huber. To my surprise I found that the width was spot on, but the tub was nearly 3/8" too deep.
The Monogram body apart from being much too deep, also had very little "tumble-home" as well. A Lotus 25/33 has a very tubular cross-section. So using photographs as reference I set about fixing the problem.
The lower half of the Monogram body up to the seem marks was removed, and replaced with panels with a reasonable curvature that I sourced from a Tamiya 1/20th Lotus 25 kit. See the picture below. No filler has been used, the shell is still in raw green plastic.
Now I found that the gap between the lower edges of the shell was too narrow for one of my F-1 chassis to fit. Ah well, it was about time to design a new chassis with some flex built-in. I also incorporated two motor mounts so that I and future customers would have a choice between a )#), )%) can or the new Pioneer motor or my favourite a mashima open frame motor.
The photo below is of the prototype Mk 3 Beardog Chassis, with a Mashima motor fitted. The aluminium Beardog gear pictured would be replaced with one of the great small Ranch Design set-ups. The front wheels are some BWA 13' mediums with MRRC BRM tyres, and the rears are a pair of old patto's 13" wheels fitted with AB Slotsport urethane's tyres.
I wanted to get this Lotus 33 looking as realistic as possible, so rear of the body was re-configured to the correct shape, using off-cuts of green plastic, again from the Tamiya kit. The correct size opening for the injection trumpets was cut, holes for the roll bar drilled, and injection trumpets were made up using bootlace ferrules, inserted into small brass tubes.
The final finishing of the car consisted of cutting a Dave Jones Lotus 25 windshield to fit, installing rear view mirrors obtained from a Supershells Lotus, and scratch building a replica transmission. The ZF gearbox was painstakingly built up from, a monogram gearbox and assorted bits and pieces from my plastic parts collection.
Using the strategically place attachment points in my new chassis the suspension was made up using fine piano wire and hypodermic tubing from RB Motion. The rear shock's were assembled using the same hypo tubing, aluminium tubing and red electrical wire for the springs.
The transistor box was constructed using layers of plastic sheet, super-glued together, and cut to shape. Wheel inserts are cut down Maxi-models eagle inserts, and if you look very carefully at the gearbox area you can see a bulkhead made from fiber-glass board and the anti-sway bar attached with RB Motion ball joints.
The driver is made up from the fantastic Immense Miniatures full Graham Hill driver kit, his head was swapped out for a PSK head that had the face mask already attached.
Paint: The whole car was painted Tamiya Racing Green, with decals from Penelope Pitlane (numbers, roundels and stripes) the Team Lotus stripes and nose logos are from Patto's.
I'm sure I missed a lot out, so if you have any questions or how to inquires please ask away.
A fantastic model of, for me, an iconic car and driver. Chapeau, monsieur!
I don't know how you ( and some other masters on this forum) manage to build a small, 1/32nd scale car to such a clean and precise state of refinement that the photos of it could easily pass as pictures of a full sized car. Someday I may figure it out. Or not. Regardless, you are an inspiration!
Simply awe inspiring Chris. The really great thing about seeing such fantastic builds like this , is that it makes me want to get better too. It gives an understanding of just how much work and research it takes to reach anywhere near this level. Thanks for the inspiration Chris. b
Excellent professional model making Chris. May I ask for some dimensions(in mm) of the shell please, length, width (at nose, front wheel opening and cockpit) and height (thickness) at the nose, cockpit(highest and sides) and engine cowl, to give an idea of how small the car really is. Do you still intend to have the body cast? Thanks Nigel

Thanks for the description and the history of the project.
You haven't mentioned how you reshaped the nosecone, the original Monogram nose has a high lower edge to provide more room for the guide, you appear to have added depth there, is this the case and did you alter the shape of the nose opening?

Thank you very much for the compliments ladies and gentlemen (Ember you had better chime in), I'll do my best to answer some of your questions.
David: The only part I didn't radically modify is the nose. If you look at the comparison photo's below you can see that. The nose looks lower because of the depth of the shell has been radically reduced. The only re-profiling I did was to slant the opening a bit.
Nigel: I have measured both an original shell, and my modified version. Dimensions are below each photograph.
Chris Wright version of the Lotus 33. Dimensions Length: 106.36 mm Depth: Bottom edge to cockpit: 12.00 mm Depth: Monocoque only: 7.93 mm Width: 19.05 mm
Extra dimensions for Nigel: Width of nose at wheel opening: 19 mm Thickness of nose at wheel opening: 10 mm Engine cowl length: 27 mm
Monogram's version of the Lotus 33. Also note that rear suspension mounting points are in the wrong position for a Lotus 33, and the engine cowl is completely wrong.
Dimensions Length: 103.18 mm Depth:Bottom edge to cockpit: 20.63 mm Depth: Monocoque only: 12.00 mm Width: 20.63 mm
As you can see from the photo of the real thing above, a few dimensions need to be tweaked. The depth of the top body (above the monocoque is still a little too deep, and the engine cover is not long enough. To answer your last question Nigel, "do I intend to cast this?" no not this one...but why do you think I have another Monogram shell? This shell will probably become a late model Lotus 25/ 25B, and I'll probably get it cast. It'll be the 7th Lotus 25/33 I've built.
