Hello, I would like to know if anyone has information about the differences between fuses wz GR31 (Poland) and F1 (France), used in various types of grenades during the Spanish civil war, thanks for everything.

GR31 is a fuse, F1 is a grenade. Specify exactly what you mean.

I think erkiyo means the difference between Mle.1935 and GR.31. If I remember correctly, the French is manufactured under license of the wz.gr.31. Isn't it?

So, they are identical in design. As the Spanish B3

Yes pajarito.You have right.Only diffrence between wz.GR 31(GR 31 is a earlier polish fuse) and Mle.1935 are markings.
Spanish B3 is a copy of Polish fuse but has a bigger theard.

I thought the wz.GR.31 and GR-31 were the same. Thanks for this new information.

The main difference consisted in changing the diameter of the thread:
fuse GR 31 (grenade wz.23) - 15mm
fuse wz.Gr 31 (grenade wz.33) - 16 mm
