37x257r, AP-T signature


#1

Hi,
I want to identify the signature from the photo
Similar on the video from Bofors-Noblekrut.
37 mm Bofors AP-T shell from 1936 [37x257r], probably Polish or Swedish-Polish.

I can’t identify the marking on the projectile, but it is not the one on the video capture; that’s the monogram of the Federation of Swedish Industry.

Regards,

Fede
