Thank you for the replies.
When I purchased the bass back in '81, one of the large screws on the tuning machines - the ones that secure the gear to the tuner - had been replaced. The originals are
slot head, a shop replaced it for me with a Fender
Philips head screw. That always bothered me. Fortunately, I tracked down a genuine Ric screw on this site.
Now, I discover the mismatched nameplate screw
I looked at the 05200 screw. It is a Philips head, straight shank, entire shank is threaded. Agreed, not correct in drive type or dimensions.
I then looked at 05221. Correct slot head drive, but again straight shank, entire shank is threaded.
My screws are slot head, tapered shanks with a short section unthreaded under the head .
Your suggestions of looking in hardware stores got me thinking: Maybe sellers of vintage hardware for houses, furniture, etc may have salvage hardware, or reproductions? I seem to recall my father-in-law had jars of screws in his garage, probably from his father. Maybe something in that collection will pan out?
I'm holding out hope of finding something aged, a closer match to the originals, to stand out slightly less than a new screw would. Of course, a Ric screw would be idea, as would a needle in a haystack!
I'll post back whether I'm successful or not.
I anticipate the search may take a while, especially if I root through the father-in-laws stash.
Thank you again, very much appreciated...
