For rail-fanning you can't beat a digital. This was just a small point and shoot. I would love to have one of those rebels, Just have to save up the $1,000 or so to get one with a few good lenses.
I tried to find out the former owner of the H-12-44, but sorry no luck. I would guess B+O or C+O???? I really don't know. I am not familiar with either railroad.
Here's some shots from the B+O museum. The place is a little cramped ,kind of hard to frame up some of the pics, but I did my best. I'll post more tomorrow.
