OK, IT WORKED. As you may know, I got this 1964 Mastro Beatles banjo and it has a small chip in the back plate, so I bought a regular Mastro banjo and had the backplate painted at the car body shop. When I sell my banjo, I'm going to include the regular Mastro banjo because all the gold trim and the newly painted back plate are an EXACT same part and if someone drops the original Beatles banjo and breaks the gold trim, you can swap it out for the spare part in less than 5 min. also If they want a perfect backplate instead of the chipped original, that takes 1 min. to swap. It snaps on and off exactly like a tupperware container lid. Here are some pics. 1st is a poor pic. of both banjos. The lighting isn't the best.
this is the regular Mastro banjo that I'm going to include for spare parts. All the trim is EXACTLY the SAME.
next is the original chipped backplate and the newly painted one from the regular banjo.
this is the Beatles banjo with the chipped back.
this is the Banjo with the newly painted backplate on it.
again, pic with me pointing to chip on original backplate.
this is the newly painted backplate.
this is a small ding that isn't visible when the bridge is in place, I found it when I took it apart for cleaning.
this is the face after cleaning
this is the headstock after cleaning.
