Bill,
I'm pretty sure the gun is a P model, decorated to 19 level. Whoever took the pictures went to the school of "leave the important stuff out", but, I see the hinged opening lever of a P for sure. Would it have killed him to take a photo of the safety, so I could see if it was pointy, like a usual P, or rounded like a V?
The 70mm chambers seem suspicious to me with his 1910 date, as well. Yes, it could happen, but, no, it usually didn't.
He is also a bit proud of it, lousy stock dimensions, white line turd pad, bad photos, and all.
I have a 19 that will fit you much better, if you are interested in that sort of thing.
Best,
Ted
