Brian:
You are correct sir, and as sharp as ever. The early (1942) one I had was indeed replaced with
British
walnut, I assume when the barrel was swapped out to a five-groove. After all the years, I forgot the fine details. I do remember I paid $350 for it. This was the same time unwrapped No 4's were selling for $179, and SKS' were $59. $350 seemed like a lot back then. If I had only kept it...
The beat-up one was birch, as is my current savage. Albeit, its an un-numbered Savage replacement.
