It's been a few days since spraying the stock, handguard and pistol grip. High humidity has prevented it from completely curing but will dry hopefully soon. A total of about 2-1/2 cans of Testor's 1265 Flat Olive over all over the red primer. As far as I can determine and from a personal friend who sent photos of an original it looks like the OD appears to match pretty well.
A later style selector switch is being "dimpled" and should be the final bit of hardware to be added to complete the project, I think.
Final photos will be posted ASAP.
