They didn't scratchbuilt. The Tigers were modified T-34s, the
Stug IIIs in Band of Brothers were modified postwar Jadgpanzer
Kanone (the roadwheels are dead giveaways in both cases), the
Hanomag, Kettenkrad, 20mm Flak, Marder II/III, Shermans and
Cromwells are real running museum pieces loaned for the shows.
