Interesting on the dates.  Another question I had was about the Black Beauty Special in the "1915" or similar catalogs.  Of course they also offer the Black Beauty and I have seen many of those, but have never seen, after viewing thousands of Bakers, a Black Beauty Special by Baker Gun and Forging. I have seen many Black Beauty Specials made by Folsom after Baker gave up gun manufacture.   
Chris had a Black Beauty Special that was for sale, more than a few years ago. I was thinking it was a Baker gun (we talked about it a few times) but, I could be wrong. He shied away from Folsom guns.
Best,
Ted
