Congratulations on your find! That's a beautiful example.

We had identical chrome-plated bayonets for our 03-A3's. We had a white vinyl cover for the scabbard. We had the carpentry shop take a couple of old 03-A3 stocks and make blank scales for us. We'd then file and sand until they fitted the bayonet perfectly. We then finished them to match our rifle stocks.

Most of us used Tru Oil for the stock and bayonet finishes. It was pretty much goof proof.
