stationary engine large filter bowl and tap. Condition is Used. This is a large filter bowl and tap, . I'm fairly sure it's of something like a lister cs. It's made of solid brass and clearly filters and changes from petrol to paraffin. This must be about 5 inches high. It's huge compared with a lister d brass filter. Also it turns freely. It can be tensioner by tightening the nuts on the back of the valve.
