Does anyone recognise this chassis ?

I bought this years ago from a racer pretty much as you see it here. I'm guessing its 25+ years old.

Wheelbase is 26cm, chassis at its widest point is 16cm, axle about the same.

The only name I can find anywhere is on the green spare cog, it says "Magic Motorsports" and 110, which I guess is the tooth count.

The body is a Sauber Mercedes and is pretty rough! any ideas on where I could find something similar? Its been on another chassis at some point as it has a second set of mounting points.

Would the front wheel usually be inset that much or should then be a bit bigger ?

Where do I get some new wheels/tyres ?

Any info is appreciated !
