I bought a new Kay M-1 back in 1968 but now haven't played it in 25 years. It remains in my front living room on its stand, strings at tension. But one day the peg fell from its position. I retrieved it from one of the f holes. Now I want to get back playing but don't know how to put the peg back into its correction position. The peg is about 237mm by 18mm with the slit running 137mm. Suggestions as to how to proceed?
