The nickel cover is super cool! It's a really awesome pickup! Judging from the stamp on the back, is it January 7, 1982? I think it's a vintage piece from over 40 years ago. This stamp is probably from Greco, right? Considering the era, I think it's a U-1000? but I'm not certain. Please be aware that I don't have any definitive proof. The lead wire is mesh-shielded and 15 centimeters long. It seems like it was installed in the rear position. Thank you for looking.
