WaM14, I used your article as a guide as well. Thanks.
My clone specs:
Near mint SN 168,73X (if I translate the original Remington barrel code correctly the rifle was made in Nov 1965.)
Original M40 barrel, again if codes read correctly tells me April 1966 (1st contract for the M40)
Correct shaped safety, 2 piece sear.
Barrel was professional installed by a good friend in Wa state. He also took my vintage Redfield mount,welded and squared off the corners. He also welded in the "700 SA" on the underside so I could use a WW2 dog tag marking set to apply the "40X mark".
Rings are original Redfield low and "1- 64" marked on the bottom.
Correct matte finish BDL floorplate/trigger guard.
Rifle was then sent off to Celtic Rifles in Tx to have the correct clip slot milled, to include the "eyebrow" cut on the front receiver ring,, the "U.S." marking above the serial number.
Receiver was then parked to match the original finish of the barrel. CR supplied the stock which according to him is copied off one of his original M40 stocks. Only downside is that the recoil pin shows on both sides. Buttplate is the original one off the original ADL stock the rifle came in. There was an issue regarding my scope. I desperately wanted the rifle returned to me in time for one of our living history displays we do every Memorial day weekend. In order for that to happen,the scope I got back was not the one I sent to CR, he sent me back one that had already been anodized BUT it was WAY too lemon/gold in color. It IS a correct mid 60s vintage accu-range with tombstone). After the display I made arrangements to send the scope to tokiwartooth and had him re-anodize and it came out much better. (It's not as bright green as it appears in the pics,skylights and flash make it look really bright),.
Sling is one that has the MRT and 1-64 stamped into the metal "D" tab.
Got very very lucky and came across an original set of E.D. Vissing scope caps, NOS in the original box. :0
I think that covers it all, enjoy.
