Tinker et al
There is no rear sight. It would appear that the gun was unfinished as there is no evidence that any clors or blue were ever on it.
This sight is very interesting. When searching to an explanation of the gun , one fellow on the 24 Hour Campfire told me what it was and that he had seen a 12 gauge that was sold in this same clearing out at Stevens.
I will take your advice and test it befor I do anything to it.
Best,
John
