This is a pre-made bridge purchased from StewMac in the 2000s. *I am listing many guitars and parts made by my father, who was a guitar-making hobbyist in his lifetime, but this is a pre-made bridge that I purchased as a sample to learn how to build guitars.* It is a bridge designed for a 645mm long scale. Although there are minor storage scratches, there is nothing that would be detrimental to its use. The saddle and pin grooves have already been processed, so it can be installed immediately. Please customize the pin holes to your liking. I would like to say it's new and unused, but it hasn't been stored with extreme care, so please consider it as a near-new item. I do not recommend it to those seeking like-new condition. Please understand the above and consider purchasing.
