Hello!! You should take much more photos of every detail you may find! A size compare would be good too if you want to get help!
Sorry for that. it was as much detail as I can get after wash it....
I didn't took it with me as I found it (not dig out) from this cave inside a park and felt wrong to do so. So I just washed it and took photo, left where it was from.
I have took other two photo and that was it.
Hope it will be helpful to id it.
My greatest fear is that one day I will die and my wife will sell my guns for what I told her I paid for them
