yeh Bill there made of what we call [auto-censored] metal, cast kinda stuff there ok tho cept ya got to use CA as come in two bits for the drive wheels and 3 for the idlers.
the tracks are hardish plastic with metal pins, i'll take pic tomorrow for ya , there not bad.
the kits pritty good even tho it has a lot inaccuracies and things not modeled at all but with around 1500 parts im only building it OOB i aint got the patience the likes of the guys at network 54 have there going all out.
having said that if you want a nice KT i think you can do it without all the extras if your not an accuracy freak.
the road wheels are in 4 bits per wheel plus a little soft cap that gets sandwiched inside so they move when u stick em on the torsion bars.
theres much debate about trumpy stuff but all in all i like it , I havent found to many fir issues with any of there kits, the historical accuracy might be not quite right but far as im concerned if it looks like what ever its sposed to thats all i care about you can do a lot with paint these days

cheers,
Graham
