I am still always searching for new Visible Gas Pump Indicators to add to my earlier research shown here on Oldgas.

This set came up for sale on Ebay. It is new to me. Does anyone know which Manufacturer used it and on what model of pump. Since it's the only one I have ever seen it must have come from a low production model of pump.

The small areas with red paint on it makes me tend to believe they were located on the outside of the cylinder. Thanks.

Looks like Bowser indicators off a C81. They were inside the cylinder. I've never seen them on any other Bowser pump, just that one.

Yes -- Bowser c81 any chance they are 4 sale I have been looking 4 some 4 a long time????

Yep, Bowser C-81.
