hkmp5sd,
The pictured rifle is not an "original first issue" that is a later production SP1. The OFI are limited to the first run of approx 2,000 rifles that were sold to keep Colt going until they could nail down the gov contracts. These OFI rifles have very rare features including M-16 bolt carriers with no forward assist marks, hard chrome bolts, no trap door single screw butt plate, etc..
I actually already a OFI SP1l. I recon wild was looking for the grails we don't own, in which case that would be a 2 or 3 digit Garand. I know of 2 three digit garands and one is for sale.
