So I picked it up today, and it's a 33 - NOT a 27.
I hadn't seen a picture of a 33 with the "bare metal" split door, but that's what the tag on the side reads - unless someone switched the tags.
I think the seller felt pretty bad since I drove 2.5 hours each way and he didn't know what he had, so he made me a sweet deal on it and a nice Glasco slider for $650. Both machines work and cool nicely. The 33 is missing the lock (will order one from Funtronics shortly) and needs some good cleaning. The slider is really clean but missing the coin mech (working on that as well) - so I don't consider it a wasted trip at all.
More pics coming in the next couple of days. They are both still in the back of the SUV - no time today to unload.
