This Proto socket set is used, has some ware/rust, and is missing some original pieces. I believe it was originally a 52 piece set but it’s missing 4 pieces that I can see possibly more. The first picture will show all of the proto challenger pieces. There will be some other brand/no names sockets/pieces included that will make it somewhat more complete but it’s still missing some original pieces. The included non proto challenger pieces doesn’t make the sizes complete there’s a few duplicates. I’ll list the pieces that I know are missing but there could be more proto challenger pieces missing than what’s listed. Check the pictures for everything that’s included. There’s an odd smell that I can’t quite figure out what is it. Maybe oil or lubricant? This is being sold as is and if you have any questions please feel free to ask.

The pieces that I know are missing:

3/8 wrench (the one that’s included is no name)

3/8 socket

17mm socket
