GW Tiger SPG | For the Record

On the 6th of May 1942, Krupp presented the first proposals for an armored self-propelled carriage (gepanzerte Selbstfahrlafette) for mounting either a 17cm Kannone K72 (Sf) L/50 or a 21cm Mörser 18/1 L/31 (some sources say L/30, L/31, or L/32 but it’s all about where you measure from and I use L/31 here).
