muscle bike schwinn huffy murray

So yeah, just like the title says, first time ever. Gonna build a bike. Bow chica bow bow... I guess I'm what they call a noob to the vintage bike scene though. So i'll tell you how I ended up here. My brother and I were at an estate sale, looking for some blacksmith tooling, machinist tooling...

Tthis bike is part Schwinn stingray and part a lot of other things. I think the frame is a Murray or iffy product? I am not sure. Front tire is legit stingray ack tire is a back stingray slick. Not sure of the rest including The hub?
