God bless you and your family! It is a standard ratchet type with the model number RKRF80 and is suitable for automotive and hand tool use. The drive size is 3/8in.
It has everything except the handle for a complete rebuild. There were even 2 flat metal clips in the kit. That part broke on my wrench, so now I have a spare. It would have been nice to have included a small line drawing showing where each part went, but it wasn't hard to fugure out.
Look around on YouTube for a rebuild vid. Doing NOT use the one from snap on themselves. They have banners on the screen covering everything you need to see. Find another one to watch.
