I am looking for an original air filter housing / oil bath.

Mike, while Lyndon gave some production years stating when the oil bath air filters were used, I'm adding some additional information here with photos.
The first photo below is on TorNorway's Snow Trac. It shows the "oil bath" type air filter that was used on the early model Snow Tracs.
Photo #2 below shows a later style original air filter that is in my Snow Trac. This type of air filter was probably used on 85% of all the Snow Tracs, Trac Master and Snow Master units produced.
Photo #3 below shows a modern after market air filter. This photo is of Arlow's Snow Trac up in British Columbia. Low profile after market air filters are very easy to find for VW engines and come in a variety of shapes. Arlow's unit is a rectangle, but I also have one that was added to my engine (after the above photo was taken) and mine is a round style. I've also seen oval shaped units.
