These are chamber dimensions from the 1870s era Parkers:

10A - .845" to .860" diameter

10B - .815" to .825" diameter

Scott, I imagine that value on an excellent condition 1870s Parker would be diminished. RMC can make lathe turned brass shells for you, but I don't think they do well with anything but black powder. That is the impression I got from various threads concerning the subject here.

well the gun came in and it does take the "modern" 2 7/8 ths 10 ga shell:) but found a crack just behind the lock plates on both sides:crying: running for front to back about 1 3/4 in long, love the gun but not shur what to do. working on a dicount to help off set the cost of repair.(great people to work with). i will keep you posted. up date; worked out a deal ! now to get it fixed, thanks dave, scott

Scott, aside from the cracks, is the gun as nice as the pictures show? That was my 2nd choice to look at when I visited Puglisi's, but when Jason said it was spoken for, I did not bother.

hi Mark, yes!! nice , unturned screws lots of barrel finish ,30 to 40% case, points wright for me .just like a new pup you don't want to put it down:rotf: thanks scott

Mark did you look at the 3 frame 10? its bottom of salelist. best ch

Calvin, I did not look at any more guns. I had a budget, and did not want to tempt fate by looking at other 10s!

The locks have been cleaned and reassembled. It pays to invest in a mainspring vise, repro or original! The scratches on the exterior of the lockplates were there when the plates were colored. I had to use my high powered magnifying glass to see them properly. Sorry about my macro photography. One of these days I'll get it! I sure wish other forums could upload photos as easily as this one.

Mark, Those cleaned up nice.Great colors!

The hammer faces are barely dimpled from use. There is just a little mark in the colors. The stock has a couple of teeny weeny cracks that I will be able to stabilize quite easily. Overall, the gun appears to have been used very little. The bores have some pitting though. As nice as this gun is, I would be willing to place a decent wager on the fact that 90% of the signs of neglect happened after the original purchaser passed away. Maybe not, but I like to think so. As always, Cheers!
