As I'm compiling a bit more data, here is a reminder of what this sort of research can accomplish:

I'll repost the key part of the above which is apt:

Quote:
"I'd just like to add a plug for scholarship.

"It's so easy now to say about Reilly that this label was from this period; this gun is dated this year; etc. When I bought 34723 in Nov 2015 there was nothing on Reilly except bits and pieces of urban legend, often contradictory and often contentious. It took over 3,000 hours of research to rehabilitate Reilly and to recreate the history of the Company, date the guns and date the trade labels. It was fun; I enjoyed that sort of thing and was often in the middle of no-where with not a lot else to do.

"However, the fact that 26584 in North Hertfordshire found its case in Virginia is directly related to that Reilly research. Donald Dallas recognized this. Others should do likewise for their favorite guns which have no records."

And Merry Christmas to all...hoping you have a full double-stocking.
