I happened to come upon a real Delaval in use in last 5 years!
The milk comes out the straighter spout and Cream comes out the spout angled a bit or on the left pail from video view...you can hear the gear drive working ....sounds quite a tall ratio. I read somewhere a Delaval could process 640 lb. Of milk per HR but I don't think I would want to Hand crank it that long.
I believe this is the same model Bruce and I have, however there is a flange base not far below the Delaval so I believe this was a benchtop model rather than the heavy cast iron stand alone model...I have seen the heavy stand version for sale on eBay.
