Congrats on the trade. I can't answer your dry fire question but I do know you can print up manuals at the Ruger website. Here's a link to the No. 1 manual. Sorry, I did not read it as I do not have a No. 1, yet. (It is on the "want" list...)
You shouldn't have any problem dry firing it, but if your plan to do it alot I would invest in some snap caps. Dry firing rimfire is a no-no do to the damage it will cause to the firing pin because it peens the chamber but not on centerfires.
