Unfortunately, a tool head is a poor place to start in trying to rebuild a Star press. It appears you have to parts to convert whatever press he had to a different caliber, i.e. tool head, shell plate, primer slide, etc. By themselves, they would bring a good price on eBay. From your photos, it appears the tool head is set up for .45 ACP. Am I close?
If you could find a Universal in .38 Special or some other caliber, you would be able to use it as a platform for the tool head and parts you already have.
