Greetings from Poland!
First; I do not anticipate to be a some very active user on this big and great message board, becouse only ww2 artilery ammunition and other ordnance, it's a narrow category what interested me.
Sometimes I can write something here, even help if I can but... like I wrote - only in this narrow category.
I'm a collector of ww2 ammunition every kind, and I cooperate with local museum in my Country in this way.
I contributing also polisch message board about artilery and ammunition.
Best Regards, and sorry for write in Englisch.
