Some quick answers:
- The 1/100 version of these cars is already made and awaiting a deadline, as well as their decals sheet too. We're just waiting for the pilots to be cast and boxes to be designed.
- As for a 1/56 version, I'm pretty doubtful due to high production costs, that might make them unaffordable to many users. We must find out a solution for making them less expensive.
- Future developments: to be honest, it highly depends on the success rate of this one starting set. Please note that, for caution, we've entitled it as "Racing Cars I", so forecasting such an eventual "II" to follow on demand. I've started collecting pictures and blueprints of other racing cars of that period, such as 1934 Bugatti 59-1, 1938 Alfa Romeo 316 and 158 or 1939 Maserati 8ctf (no ERAs found so far, sorry!) - but some of these are rather crude. Please any decent blueprints you might have would be warmly welcome!!!
- Single cars: sure, we'll start soon selling them by the unit too, as well as separate decals sheets.
(BTW, I do love Alfas too - I had a 355 for a number of years, and still miss it now!)
