If you are looking at the Workingman's 12, it is a 12 inch speaker. The Workingman's 15 had a fifteen inch speaker and a little more wattage. I keep reading you mentioning the 15", but it doesn't have one.
I owned the gen one WM 12 with the step-back cabinet. I played hundreds of gigs in bar sized rooms with just that amp, no PA support. In the 90's, that amp with a MM Stingray was heaven. I had zero issues being loud enough with a drummer and two guitarists who were reasonable with volume. It has a functional eq that works well. These days, I use the Rumble 100, which with I can get a sound close to the old SWR, but easily half the weight.
If I had more space, I would buy a WM 12 for nostalgia. A first gen with no rust issues may serve you well, but not sure the amp can be serviced easily (parts may not be available) and the original speaker may be difficult or impossible to find. But even so, they were workhorses designed to be played and they were reasonably bulletproof except for the tweeter.
If the price is right, go for it!
