Looks good. I have heard that some years had some lighter Italian walnut. Others will know the details better. I did just read that some process goes on with linseed soaked rags that cause spontaneous combustion. I can not remember if it was boiled or raw linseed oil. In any case it does not hurt to be careful.
How well did the sight and extractor cut line up? Did you have to fudge a little under or over tightening?
Also it would not hurt to check the relative head spacing. An  unfired case in the chamber without the firing pin removed will tell you a lot. Since you are pretty handy with tools, checking the difference in feeler gauges between the bolt rib and receiver, with the bolt pushed forward then backward, would tell you a lot.
