Are the wheel/hub caps from a Mercedes? yellow & green
the grey wheels are intersting
what is the front end thing from or for? I can not get it to fit a tjet, magtrac
kind of like a Sears front end but bigger?
check out the tjet pusher
the grey wheels are Tyco Pro ... used to put them on AFX for the look and width and of course slip on silicones.
split many, not understanding the difference in axle diameter between the two brands.
the other wheels might be aftermarket customs from Auto World/Oscar or might be from a Lionel/Marx/other brand
the "front" wheel drive t-jet is very interesting and I might replicate.
as JoeZ said about the weight.
As others have said the greys are Tyco Pro, always loved those on AFX, hated the skinny, skinny fronts though. The spinners are actually fairly hard to find and are from only one body style.....Aurora Vibe Hot Rod (coupe and roadster)..........NOS sale for $40 a set of four!
