Let me just say I am not at all questioning the date of the rifle, it is clearly a post war 1955 or 1957 gun, micro-groove, peep sight tap, etc. even the weaver scope mount. The gun has been in the family since the mid 90's so turnbull could be a possibility (could have asked him a few weeks ago, oh well). I only question why someone would go to the trouble of spending serious bucks to case harden a 39a. The gun is not reblued, the screws on the receiver are perfect, the wood is clean. I can see no signs that would lead me to believe the gun was restored in any way. I was just curious if another similar gun had surfaced. My best guess is this was done as a presentation gun, or employee gun. With no records, we'll never really know. I'll see if I can get it in doug's hands at the NRA show, he may be able to shed some light on this gun, or be able to tell me who was capable of doing that level of work.
