Good morning (evening?) everyone, its been a while since my last post, hope everyone is doing well! I found this pretty nice piece of trench art at a local antique fair. I was hoping someone could help identify some of the marking's. That would be supper helpful. If anyone needs clearer pictures just let me know. Thank you for looking at my threads and for your replay's!
