I have a 66-1 2.5" that was issued to a La. State Fire Marshal. Its like new with box. I've been wanting to add a 66 4" to my collection. So, lately, I have been searching classifieds, gun shows, and GB. Most, in nice shape, seem to be going for around the $7-750 mark. Others, in mint shape, with box, papers, and tools, go for a bit more. Haven't found the right one yet, but they aren't getting cheaper. Lol
