My understanding, after several days of web browsing, is the 1922 Bowser Advertisement indicates you could purchase an after market Bowser kit to convert your piston pump Bowser into a visible pump. Either a single 5 gallon or a double 5 gallon, with side lights and an added top globe if desired.
Is this correct?

Shown in the black background photo panel, the before visible on the left, after kitted on the right.....3 different piston type Bowsers....but not limited to these Bowser piston models.

The the middle two photos show a Bowser 245 before and then converted to a single 5 gallon. Correct?
could have easily been a double 5 with globe.
