This is a rare(ly) seen 1.5 L car. Try to hold onto your lunch.
Stebro Mk IV - the original in action at the 1963 USGP at Watkins Glen
Matt's Stebro Mk IV
The Mk IV raced in other events after its single F1 start, with the mechanicals and appearance changing over time. The slot car was built using a photo of the car as it appeared a few years ago. Obvious among the many differences are the engine cowl, nose, and wheels. Since the model was built, the prototype has apparently been restored to a form that is closer to its original configuration in the 1963 USGP.
I can understand why some of these cars are rarely seen. The Mk IV prototype was...ummm...not very good looking. And somehow, I made a model of it that is even less good looking! But I'm still a fan of Peter Broeker, the privateer owner and driver.

Dave makes a great shell of the P-48, but that ran in the 2.5 Litre Formula, but the one that Mark really wants is the BRM P48/57 Coventry Climax, it was BRM's first entry into the half ton era. (picture below) It's quite a lot smaller than the P-48, but I believe it's a distant cousin.
BRM P48/57 1.5 Litre Coventry Climax
BRM P-48 2.5 Litre BRM Engine.
Here's David Lawson's excellent P-48 from the Dave Jones shell.
The Emeryson in 1961 and 1962 was powered by a Maserati engine in two races and the Coventry Climax 4 cylinder 1.5L in 3 or 4 races. Phil Kalbfell crafted a superb model of the Emeryson Climax for the current VRAA races.
I believe this is the Maserati powered Emeryson
And here is Phil's rendition of the Emeryson Climax.
And then there's the v-8 version, this transitionary period between the 48 and 57 is very confusing.
I would suggest there is confusion because:
1) Folks have called the smaller 1961 1.5L car with the Coventry Climax: a P48-2 (rarely) or more often a P48/57 or just a P57. 2) The successor car built in late 1961 for the new BRM 1.5L V8 engine was also referred to as a P57 by many but I prefer the P578 designation. Chassis Number P5781, dubbed "Little Miss Elegance" by the racing press and then as "Old Faithful" for its long and successful racing record, was the first chassis of this model type. You can see an emerging work in progress and a picture of the beautiful P578 as it originally appeared in David Lawson's post of today. 3) To make things more complicated the 1961 car (let's call it a P48/57) was refitted with a BRM V8 engine in early 1962. Ginther drove one of these P48/57s at the 1962 Monaco Grand Prix (he crashed it) because the team did not have two of the newer P578 models available. The P48/57s were also campaigned by customers with the BRM V8 in 1962.
As far as who makes/ made what shells:
As far as I am aware, Dave Jones is the only person who has crafted the 1960 P48 with the 2.5L BRM 4
Nobody has made the P48/57 (the 1961 car with the 1.5L 4 or the 1962 version with the BRM V8 engine.) At least not commercially.
Everybody and his brother made the P578 either in the short lived stack pipe version or with the later low exhausts. I only exaggerate slightly. I suspect this car has been popular as a model for three reasons 1)Graham Hill won Driver's and Constructor's World Championships with this car 2) The P578 appeared in Championship Grands Prix from 1962 and into 1965, the heyday of the slot car modeling boom. Perhaps it was logical that the larger toy companies would model a well recognized and successful car, and 3) the stack pipes (although not used by Owen Racing after the 1962 Dutch Grand Prix) gave the car a rather distinctive look.
