Russell,
I will have to re-upload the photo of the proof marks. I can read them better in the photo than with a hand lens. That will be later today.
The engraving on the barrels, to me, certainly looks original to the gun. I will work on better photos.
The gun had passed through the hands of Thad Scott a dealer here in the southern US. I was only able to see his import stamp from the digital photo. He was not helpful.
Any ideas on the right barrel? You can feel the grooves with your finger but they are hard to see. Are they there to stabilze a slug, or to spread shot in a wider pattern?
Can you recommend any references I should look through?
Thanks,
Lou M.
