It looks like a BM23, just missing the rail around the top. Beverage Air is a commercial grade unit, and a new one is on the higher end of the price scale. This unit is comparable to one made by True. If everything on the inside looks good, fan works well and compressor sounds ok, then you may have a good find. I would mention the missing rail, broken lock and overall condition is not really what you had hoped for. Also know that if the compressor goes out, it will cost you more than it is worth to buy a new one. Then break out 2 nice new $100 bills and work it from there. This is my opinion only. I do enjoy CL negotiation. Good Luck.
