3/7/19 - This is an antique Webley Mark I service revolver from the 1890s. The revolver is all matching and original with about 75% blue remaining, showing a nice profile but very little finish remaining on the grip frame and a fair amount of thinning to the serial. Excellent, shiny bore and the revolver's action appears tight/correct. Four inch barrel. The back of the grip frame is marked NSWG 17, which I believe stands for Naval Special Warfare Group. It is also marked 6/93, which may be a manufacture date but not positive. Last marking is either a 6 or a G over 13, but not sure the significance.
