I recently purchased a Berkel non-electric, lever operated meat slicer and I'm in the process of cleaning it up and restoring it to as close to new as I'm able. It's been sitting in a shed for the last 15 or 20 years so it needs a real good cleaning most of all. It appears to be all there and now that I've got everything moving again I'm anxious to see it slicing meat for jerky, but first I want to completely dismantle it and clean it up. As near as I can tell, it was made around 1940 or a little later judging by the patent dates that run from 1928 to 1940.
It's fairly small as commercial slicers go but it still weighs a ton. I suspect that maybe these would have been made for smaller stores and cafes.
I have a serial number, but no model number and in my research I've been able to find info on Berkel slicers going back over 100 years, but nothing on a lever drive. I'd sure be grateful for any information that you folks can provide.
