To answer the one question, I like semi-autos over revolvers, though I have some revolvers, both modern and C&R.
The photo was just a snapshot, I stood on a chair and fired off a few pictures, and picked the one that came out best. I really didn't think about taking a picture until they were all out on the bench, then the thought came to me.
I picked up the Reising about a year ago on the auction, AA as I recall. It's pretty accurate for a gun made around 1920.
