Charlie, in the link that you posted it says that this was a 6 gun consecutive SN run.
JAY; I agree on the Gunbroker links its aggravating when you want to reach out and ask about a particular item that sold conversely the privacy as a buyer is comforting. As Chuck mentioned earlier they are consecutively numbered and now we know they originated from the same source and approximate time period. I think you could contact the gentleman that runs the web page link I sent and he may be able to help locate them if you wanted to find the owners. It would be nice to have a pair of consecutive serial numbers. Its not necessarily finding a needle in a haystack as it would be for a general production run. But a pair of consecutive serial numbers from a six gun run would be 1/3rd of the market, lol,,,,,,,,

You have an awesome 10-22 Jay....
