I picked up these on Sunday in the Poconos (thanks for the tip Tim and Slider-Bob!)
The one on the left is the "27a" that I really wanted, the Glasco GBV50 was a bit of a throw-in. I got it pretty much thrown in because the "27a" is actually a 33. I drove 2.5 hours each way, but the seller never looked at the little plate just about at eye level on the side of the machine.
Both machines work, both need a good cleaning. The 33 needs a lock and to get the proper decals applied. The slider has a replacement coin mech (thanks again Slider Bob!) that I will install when I'm done cleaning them.
