2025/05/08 Added photos 17-20 and descriptions. I apologize for the images being found online. I recognized the shape, but it took me a while to remember. For reference, the shape is very similar to a Fernandes FRT-5PRO-TRS, although I can't compare them directly. They may be the same model and therefore compatible. Also, while searching for FRT, a Jackson FRT type listed on Mercari is very similar, including the inertia block, so it might be the same model (photos 18-20). 2025/03/11 Added bonus item. Unbranded, licensed Floyd Rose type tremolo set including nut and spring hangers. The tension bar needs to be sourced by the buyer. GOTOH WRH-1 included as a bonus. High-quality product with good processing accuracy and plating quality. Actual product dimensions (approximate values): Nut width: 42.3mm String spacing: 10.5mm Stud spacing: 74~74.5mm Anchor diameter: 10.0mm Stud diameter: 6.0mm Shipping via Takkyubin Compact. Thank you for your consideration.
