Licensed FRT type tremolo unit, new but unused. Judging from the shape, it appears to be Takeuchi tooling, but it's unknown if it's made in Japan. Studs and anchors are included, but it's unknown if they will fit. No arm is included. String spacing: 10.5mm Stud pitch: 74mm Tone block: 34mm From photo 2, the fingerboard radius appears to be around 300. It seems likely to fit 80s-90s Japanese FRT type guitars, so how about replacing a worn-out knife-edge bridge? Thank you for your consideration.
