Hi @ all!
Hope to get some answers in this forum. I got an very old airrifle from my grat-grandfather here in Germany. It must be some kind of GEM rifle. It has an octagon barrel. The caliber is 4.5mm / .177 I think.
I read in the Blue Book of Airguns that it could be a Haviland & Gunn airrifle.
Maybe some of you can give me more details in this rifle.
Here are some pictures of it.
Thanks in advance!
Heres 3 i have, but None of them Appear to Be Identical to Your One.
