Have had this Blue Note for some time. Bought it with the worn out backglass, and since there were only 226 of these made, had figured out that a NOS back glass would be a tough find. Here are some photos of before and after.
Worn out backglass with peeling and missing art work.
The backside with tape and possibly some clear coat.
The new backglass from Steve at Mayfair Amusements in NYC. Steve sent some photos of the slightly worn off back silvering. Looked great to me as it is a 100% improvement from what I had. Could not be happier with the replacement.
