Thanks for the quick replies and great information.
I am not sure how the CMP got them unless they were sent back with other "equipment" from some organization that received things like rifles and accessories from the DoD. Between VFW Posts and ROTC there are probably lots of opportunities.
The guys at the CMP may not be experts on this stuff so they sell it because they received it to sell.
Money goes to a good cause so I am only disappointed that it is not GI, but not upset at all with the CMP since I have received some really nice Garands from them over the years.
thanks again for the great information
