Posted By: Gpmp National A 38 Sight glass panel question - Sun Jan 01 2023 12:03 AM
I have two porcelain National pumps. Both are complete and seem to be unmolested.
One is a 38A and the other is 38B. The sight glass metal panel is different. the b panel is taller. The trim is missing but looks like it attached to that panel.
b panel is about 3/4 of an inch taller.

Anybody seen this before? How does the lower ad glass trim attach to the B panel?

thanks in advance,
Greg
