I don't have one of these Rick, but know there are some assorted web sites that deal with them, one is on
www.gunboards.com they deal in old lever actions.
It is amazing how some groups of collectors are helpful and others... aren't.
The 1 of 1,000's are very rare, but I imagine your book covers them also? If not I bet it gives you a good start.
NICE looking rifle!!
