This piece has more creative features than most any rifle that you will ever see. The buttplate return is the patchbox release. I thought that maybe the wood had shrunk back because there is a 1/32” gap along the return. Nope it’s there by design.
This piece has inlays inside the ramrod groove.
The inlays in the buttstock are amazingly intricate.
The lock appears to be hand made.
I believe this was made by someone who had experience in gun making and understood longrifle architecture and design while having an extremely creative side. This one was likely made in the 60s or early to mid 70s.
I call these ultra contemporary. A definite modern take on a traditional style.
