Is there a stone in the pouch? Is the parkerizing "fresh"? Are there any scratches under the parkerizing? One think that concerns me, is there is no sharpened edge visible in the photo. I don't recall if any maker sends a parked knife out with a coated edge dating back to probably WWI and certainly WWII.

RMK did "a few", and I don't know what that exact number is, but is is small. Perhaps half a dozen and probably less. It was something that the shop determined they didn't need to do and add to their already backlogged work load.

I am trying to find out if there is any recollection of the model(s) that may have been done, but would assume it would be a military model(s)

So, to the knife at hand. It could be late Viet Nam, say 73-75. Without having the knife in hand, the original stone could shed some light on vintage. Wether it is shop supplied parkerizing is unknown, and if there is any recollection as to the time frame when the few knives that were done, that could narrow it down. Thing is, it is very obscure, a blip on the screen, and there is only one person that MIGHT recall it, but I would't count on it.

Therefore, absent of any other "evidence", I would not claim it was shop parkerized, unless I can come up with something that tells me the knife falls within the time frame the shop had it done. Even then it would only be a maybe at best, you could not say definitively it was shop supplied.
