I got this MAC V5R 1/2" ratchet at a yard sale.

Not sure how old it is, maybe one of you knows. All of the tools were encrusted with the hardest crud I've ever seen or the oiliest crud. The rat wouldn't shift, and I thought it may be damaged until I opened it up.
It's held together with a retaining ring. It was easy to get out.

The innards were a typical design, but I don't know the name.

The head has 50 teeth, and the pawl engages two teeth at a time.

There was a trick to dismantling the head. I thought the selector was staked on after the head was assembled, and it held everything in place, but no. You lift the selector up and turn it until the ball and spring release. It took a while to figure this out because of all the muck holding it together.

Here's the head cleaned and assembled (still a little scrubbing to do around the edges).

To assemble, you insert the selector into the head, put the spring and ball in the selector hole, then insert the pawl and pin. Next take a pin punch and push the ball into the selector hole and rotate the selector to the center. Install the selector cover. Now the head is assembled and you install it in the handle. Replace the retaining ring and you're done.
The ratchet is lubed and ready for use. The action is somewhat smooth, not buttery, but good enough. The handle fits the hand nicely. I've got loads of 1/2 rats, so for the right price someone might convince me to part with it.
