$300 - $450 price guide suggest - looks lack luster and boring however pictures can be a bit mis leading, could look a lot better in person these early 60s Wms. pins are either hit or mis Cevans82
So you got to go with your 'Gut' on this one.

Also ask the cat if theres a on/off switch under the cabinet ?

Well..........the older EMs (not sure what year they changed) were always on,
if plugged in the wall the transformer was 'on' having a Switch (or adding one )will turn it off
if it's an unmolested pin it will not have a on/off under the cab. if it does you may want to look even harder for hack jobs to the start up sec. - it can be a headache undoing a free play mod done 30 years ago that now looks just as dirty as the other components around it.

Of course with Wms. being sold/ bought a few times, I think around the early 60s Seaburg the jukebox co. took them over and went to a longer drop front end cab. just to fit there coin mech.
but only for a few years then went back to the std. form.

Yeah check it out. I've seen a few dogs on the IPD that looked a lot better in real space
and for the right price and distance could be a worth while project.
- good luck
