Man those are some killer blanks. IMO #1 is too much for an A-grade and I'd agree with KY Jon that 2&3 are seemingly the best of the five for your Fox. I really like the straight grain of #3 and think it will work beautifully with the lines of the Fox action. I have a later Philly A-grade 12 that has really nice straight grained wood that gets a lot of compliments. Not sure which species of walnut Fox used in the 20's but back to your blanks - I don't think you could go wrong with #'s 2 or 3 in the lineup.
