'73 240z Brake Master Cylinder

Hey gang, I've got a used BMC off of my low-miles 240z. Took it off and put on a new one before realizing it wasn't the problem at all.

So now I'm getting rid of my used one, rather than going through the process of putting the old one back in and returning the newer one. I'm thinking of selling it on ebay, but I'll see if anyone has any offers here first. 7/8 bore, no reservoirs included. No leaks, in fabulous condition, with some surface rust on the bleeder screws. Anyone interested?

Thanks,

brett
