Hi, I have a friend who's doing some work on a Dixie banjo uke similar to those depicted below

and he's looking for original tuners or ones that are narrow enough to fit the holes without drilling. Any help will be appreciated. If you have any ideas, etc. send me a PM and I'll send you his email. TIA, g2
