Holy moly!! I learned more in 10 minutes of reading that first article than in hours of other internet research. That is an incredible amount of information. I have a 1930 91/30 and a 1936 91/30 that came to me with stocks that were definitely correct for their year but were painted or had incorrect finishes. I stripped off the paint and refinished both with RLO. Looks like I need to get them out and redo them correctly! Thanks again!
