Thanks Charlie for the big amount of information about my S&W Victory !

The marks on the left frame aft of the cylinder latch that you thinks are maybe a broad arrow don't seem to be one look at the close up pics (pictures one and two) !
It more seems to be à crown on two letter (second one is propably an R). Below seems to be some crossing line and at the bottom a P.

Third image is a "similar" markings on a britsh Webley Mark I own!
