This is a modified bridge from a Squier model from around 1999. I removed the original bridge and replaced it with a tremolo block that fits the plate, which I found online. The saddles have also been changed to brass or steel. This is recommended for those who want to upgrade their used or current Squier guitars. I'll include the original inertia block! The saddles were vintage, but they were so bad that I threw them away. Please understand if I couldn't find them. I will disassemble it and ship it flat.
