I'm in process on this really nice Maurer Concert model from the thirties that came to me with changed tuners that rotated the wrong way. I need the reverse gear type with post spacings of 1 3/8" and post diameter of 1/4". Does anyone out there have or know of someone who might have either originals or replacements for these? The guitar is really nice and deserves the best I can find. I'm including some photos of the restoration for your perusal.
