Here's a look at a one of the SMEC kits as supplied, a 1-1/2 litre Alta....
Hmm, a bit of work to do there... especially if you wanted to do a slot version. Here's another SMEC built up as a static model at the time, the Bugatti - nice job! Hand painted, no Dremel...
And as promised, an unfinished rail chassis I picked up on ebay US many years ago in a lot... It came with the guide soldered on, but without any pickups - I added these to try the car on Jeff Davies' rail track in Wales, but never got the chance. That's a Pittman DC-60 motor by the way, which seems to have been a favorite of the early US rail cars... The car is pretty much as found, except that the larger tires were on the front, not the rear, so I reversed them. Not sure why that would have been done... I believe that those are Eldi gears, one of the first accessories made for rail cars, in about 1956 - mail ordered from England by the US builder, as were most parts! And you can see the nice metal wheels and rubber tires that supposedly inspired Southport, etc. to adopt 1/32 as the official scale back in 55-56....
