Parker 1866
 

I'm trying to find the value of a 1866 Parker Bros shotgun, serial number: 048 with the patented date Nov. 13, 1866. It was just brought in from an estate into my antiques shop here in Deerfield Beach, Florida.
It needs restoration but I think a collector would prefer it as is.
Any advice would be appreciated

Pics would be very important here. Are you saying it is a “T” latch action?
If you don’t know, that is why pictures are needed for us to give an opinion.

I would love to see some pictures of this gun.
