I have always had an interest in refrigeration and fridges and I have recently acquired this 'vintage' Prestcold. Not really old (1961) but old enough to be a little different. Prestcold was a common British make of fridges formed from the former Pressed Steel Co. (I live in the UK.) I would really like a Monitor Top, but they're not so common over here, and I don't think my wife would let me have another fridge! 
Anyway I've posted some photo's in case anyone is interested. It looks like a rotary compressor, mounted horizontally. The compressor itself I think is on the right hand side of the shell, it has a small sub-condenser - I think - that goes back into the compressor shell to cool the motor. Because the shell is on the high side it takes quite a while for the refrigerant to be liberated from the oil - about 10 mins before any cooling at all. (I thought it was out of gas when I first plugged it in!) You can see it fully frosted over after about 30mins. Nice large accumulators - this fridge has a charge of 14 oz of R12. Surprised to see it only seems to have a filter / strainer - no dryer - I don't know if this was usual for this age fridge. I can't find much info on it (or the compressor).
I have rewired most of the old rubber insulation - but still have a lot of work to do.
