I have a 1974 Glencoe 19', has the WJ with a stainless PJX impeller, and diverter. Stout and solid boat, for a 1/4 stringer boat. It has the 'double step' deck, similar to my Eliminator Day Cruiser. Has considerable hook on the bottom.
Best run was 71.8 gps'd up river with ~500 hp BBC.
If I remember right, they were built in Anaheim or Santa Ana. I've only seen one other like it.
