jbm,
If you looked at the Hand Guards section in the link Wayne attached back in reply #3 you've seen you have a Inland hand guard made by S E Overton.... O I.
It sure matches your stock in color and grain flow nicely.
After you lube it up, let us know how it shoots.
Early S'G' like this are sought after. Hard part is finding a correct stock for them. Rare and Pricey when found. Stamps are often Faked, so beware.
Thanks for sharing it with us![]()
