It looks like about 1922 Bowser started offering visible pump conversion kits for their pre-visible pumps, one of which was the later model, sliding door cut 241.

I found a 1922 ad for such kits, not much info other sales blab, but very interesting.

This single, 5 gallon cylinder kit was called a Bowser C-2, but I haven't found any Bowser literature on this kit identification. Can anyone shed light on this?

Just prior to this Bowser kit, I believe American Oil Pump & Tank had been offering a similar 5 gallon visible kit......but I could have the offer order mixed up.

The Bowser C-2 visible kit was more elaborate with a locking selector valve and lighting, from what I see.
