Can you help me identify this cooler

Hello.
I acquired this machine several years ago ...but know little about it.
From reading the lables ...it's a Kelvinator water bath machine manufactured by the Grandale Company Ltd. 35 Jenkins Street, Toronto.
It is approx. 44" wide, 36" high, and 29" deep.  The top is removable and is split down the middle length wise.  (I've tried several times to attach a jpeg ...but no luck)  The original refrigeration and water bath propeller motor still work great.  The only thing that needs some work is the "blades" of the water bath propeller (shaped like a washing drum) are quite corroded.  Any idea where (if) I can find a better one?
Any idea what it's worth?
Any info would be appreciated.

Cheers

Here is a photo ...I hope.
