I'm new to the forum and I recently picked up this revolver (V437588). I have been seeking one with a USCG marking for a very long time. If any one can provide any info on it, I would greatly appreciate it. Eventually, I'm planning to get a smith and wesson factory letter for it. I'm hoping to get some vintage ammo to make a display. I was happy to come across this forum from a simple web search! There are a lot of great guns on here!!
