Yuh NSuh?
That's it. Grips are darker wood, but that's it near as I can tell.
Police used them as "handcuff case guns" back when I got mine. They were so small could be stashed almost anywhere. Came in .22LR, .22WMR, and with various barrel lengths out to...er...maybe 3.5 inches. Subsequent stuff included grips that folded down for better hand purchase, and (I THINK) maybe a neck holster set up.
They were last-ditch guns. Always struck me that they could be a liability, because no one would believe that they were REALLY guns. I read once that the .25 Ravens got a lot of people shot, because they looked like toys. (Also read that at one time more people in some urban area died from the .25 Ravens because they were everywhere, and people got shot, infected and didn't go for treatment for the GSW.
I got mine for tent camping when I did a lot of solo motorcycle trips and camped in obscure places. First round was always birdshot; subseqent rounds were regular long rifle. I figured I wanted to 'inform' someone I had a gun if they were coming in my tent at night, and that the #12 shot could possibly sting faces and cause a reevaluation of priorities.
(changed single-shot to single action, ty.)
Maybe 15ft reasonable accuracy for the one inch, but if I was more than 15 ft away, I didn't need the revolver. I also carried "feet" with me when camping alone. I would use them.
