SOLD.
I have a like-new condition pre-Fender Workingman's 12 combo. It hasn't seen any action for at least 5 years, and has been sitting in a cabinet in my practice room. Works perfectly, with minor scratchiness in the pots. I worked a couple of them until the scratch was gone.
It's a great practice amp and good for small gigs. Also popular with the DB crowd. I think it would be a nice keyboard amp, too. Here are the specs from the SWR website. These are for this unit's vintage.
Power Output:
120 watts @ 8 ohms (internal cabinet)
160 watts @ 4 ohms (w/ 8 ohm extension cabinet)
Speaker complement:
(1) 12" Custom designed SWR driver
(1) LeSon TLX-1 tweeter
Dimensions: 15.5"W x 22.25"H x 15.25

Weight: 50 lbs.
Production Period: 1994 to 2006
Final Retail Price: $714.27
Anyway, let's say $300, or tell me what it's worth.
SoCal sale only.
