I will give you what I can on the original owner mentioned in the PGCA letter if you will share the name with me. My email is wilmrph@verizon.net. I have a bit of research material on early competitive shooters.

It is a Dollar Grade gun and I would estimate it to be a $200 Grade judging by the level of engraving and the bolster engraving.

I, too, have some information on early shooters in Missouri and those who came to Missouri to compete up to 1898.

Tulsa find
 

Here's what I got in my letter. No stock book or order book for it but did get returned for some work. It was returned on August 11, 1884 to clean and rebrown barrels($5.00) and repair action(free). On October 30, 1886 to fit new 30 in barrels to shoot same as old, cost $45. Then returned again to restock and return his old stock, cost $10. Every time that it was returned, it was returned by George H Palmer of Bellefontaine or Kenton Ohio. I did try to research George H Palmer but could not come up with an occupation. Anyway if anyone has the other set of barrels for serial 1227 I would be interested in purchasing from them.

Sorry I couldn't find anything of value on your "George Palmer of Ohio".
