You are right, it should have. But it could be an error or simply a bad stamp on the part. I don't know. According to the witness, over 90 years old, the plane came down at night and there were woodden parts in the crater burning. It was downed by German artillery fire. They went out to pick up remains the morning after. I'm very careful when I acquire info from witnesses, because several times in the past they mixed more downed aircraft in the same crash site and it's difficult to understand the real thing. We found even a screw for wood and large roundels like I saw in a Mosquito crash in Scotland. I went out for another type of plane, a lighter fighter bomber, but came out this one, as a surprise. We should have another witness from the same place, I think, with more info. Furthermore, I have minimum one downed crew to check in at least two cemetery list of death in the surroundings. Stay tuned...
