BB - we must read the same sources. I too have read that the P-63 is alleged to have turned up over Danzig (Kronisberg - [sp]) and Berlin in the very last days of WW2.
On another - unrelated - note: I saw Valkerie over the recent holidays and was generally very impressed with the attention to detail (trucks being the exception). It opens with the Count's unit being straffed by RAF P-40's in Tunisia which is a nice, realistic touch. And there are multiple, very dramatic appearances of JU-84 'Auntie Ju' transports throughout.
Chairs from the land of sun, snow and ice. No GW here.
