Is this master cylinder toast?

I pulled my tank and yikes! Is this master cylinder salvageable? the front brake worked at least adequately when last used a couple of months ago.

Can't tell until it is taken apart and cleaned. If it has pits in the bore it will need to be sleeved.

Does it hold fluid? Remove the rubber cover over the linkage and check for leakage there. I just rebuilt the M/C on my /6 and while waiting for the rebuild kit I disassembled the M/C, wire-brushed the exterior, degreased it with Gun Scrubber, then painted it with a brush.

Nah, it's fine. You can have them blasted an re-sleeved. That cost me about $80 total last I had it done, plus the cost of a rebuild kit.
It's cheaper than buying one that's already been done or a good "looking" one that you can't know if it's trustworthy.

Since you are on the subject of re sleeving, let me ask this:

My master cylinder was leaking. When I took it apart the piston, due to the bike sitting in my cousins garage for 30 years, the piston had dug a groove into the bore from sitting in that one position for 30+ years, that was probably fairly deep maybe .032" or so. I ended up buying a new master cylinder for it to the tune of about $280. Could the bore of the master cylinder have been re sleeved under these circumstance?

Yup! Any damage to the sleeve means nothing. They'll just pop that sleeve out and press in a new one, matching the new piston. Just like a normal engine cylinder and piston.
It's also miles cheaper than just buying another MC. I had a junk MC and paid 80 or so for the re-sleeve then the cost of a rebuild kit.
80 bucks included blasting and re-sleeving. After that, I used POR15 hardnose paint to coat it. Much hardier than any other paint.
