Thank you.

I just checked the fit of my tuning wrench (square socket) on the tuning pegs and there is too much play; not as snug as I would like. I've read suggestions about the desirability of using a 6-sided socket and one person mentioned using an 8-siced socket.

I value your advice and suggestions.

(Incidentally, this was an ebay purchase, OS15, probably 1967 [parts sheet inside the case with that date], and in very good condition. It appears to have been treated gently.)
