old frigidaire set

Very nice!  Lucky find in your part of the world. 

This would appear to be for a commercial display case or other medium size application. The motor is probably a Leland brand; repulsion-start induction motor as well. Or it may be three-phase. It is hard to tell in the picture. 

It could have been R12 or possibly sulphur dioxide originally. The drier would indicate that somebody replaced the SO2 with R12 in the past and continued to use the system with R12.

Thanks for sharing the picture! Hope to see more after you get it in-hand.

EDIT: That would be a 40's model machine, as well, based upon the overall design.

Neat unit!  It would be hard to compare that to the US models from a year-of-production standpoint. All I can say is that similar ones here were used widely in the 40's and into the  50's. 

Also love your new avatar.  Is that a drawing of your AEG Santo fridge?

@ turbokinetic: Yes. Thanks. That drawing is from an 30's santo advertising leaflet for the flat hermetics. In those days electrical refrigeration wasn´t common in germany. They had to demonstrate their products and convince the wealthy customers of the advantages of constant cooling. Most of them still got ice blocs from service men once a week. No more melting water in the kitchen and a dry cabinet. What a technical progress... I also appreciate a frozen evaporator very much. No mold and slimy drainig holes as in the modern plastic products.

@ redtangox: Shure I'll do.

I plan to pick up the unit next month, 16th. Then I take my summer vacation. I also plan the resurection of the santo(s). I've to investigate the comprssor shaft sealing first. I hope that the sealing isn´t to complicated to service. Otherwise one of the hermetics will be the first attempt. I love the archaic style of the motor-compressor units more.
