Thanks for your response. Here are some detalis.
SN?-H1515 - on the underside of the upper hand guard, on the bottom side of the magazine,on the clamp that connects the stock to the rest of the rifle.
NO.5 MK1 U-King - on right side of the barrel.
C.A.I. ST.ALB VT- under the barrell.
M/470 (the "zero" could be a "C"

- on the left side of the front site assembly.
47A - on the barrel clamp with sling swivel.
Bolt handle hollowed out.
Flash hider, front site and bayo lug are a single unit.
The mfg was not clear to me. The wood has a few dings, no pitting on the metal. I have cycled
rounds with no obvious problem. Have not fired the rifle. Bore looks good. Sorry, I have not image. The weapon was purchased from SOG some 10+ years ago. I hope this helps. Many thanks for your evaluation. Dan
