@ Paul
I cant remember what the chassis number is but the body is from KYW:
Aktiengesellschaft Ferrum Panzerung für m.SPW, Werk Laurahütte, Siemianowitz bei Kattowitz (Now in Poland)
@Simon
yes as Pzkpfw E says, it is made up off original parts and replica.
The original wing has flak damage. the landing gear is original aswell, but I dont know that much about it, I am mostly working on the 251, 17pdr and M10
