I have no idea where I'm going with this other than curiosity. Following is a list of G&B T series visible pump models I have documented over the years. Does anyone have any other model numbers to add to the list?

Can you tell me which models had the taller 73 inch skins on them? I have and have had several of these pumps and can't figure out for the life of me which models had the tall skins.

Thank you!

I have a G&B T-177 stamped as a Model 2 and it uses the taller 73" skins.

Is it a 5 or 10 gallon pump? I used to think that only the 5 gallon ones had the taller skins, but after buying a another one with 73 inch skins on Sunday I don't think that is correct.

I believe all of the the T-176's had 68 3/16” skins and the T-177, T-178 and T-179's had 73 7/8” skins. However I cannot confirm that this is correct.

Thanks Daryl.

Thanks Richard.

The T-177 is a 10 gallon pump with tall skins, I have recently looked at a G&B 5 gallon pump that had the same (taller) skins. The 5 gallon pumps such as the 67 should be on the list of G&B visibles.

So all the 73 inch skins are 9 1/2 inches at the top and 18 inches at the bottom? I'm trying to figure out if the 5 gallon and 10 gallon pumps take the same skins. I'm guessing that they do and the difference must be in the bottom jar casting.

The reason I didn't include the G&B 67 is that I was only researching the T-176 - T179 models.

I believe all the skins are 9 1/2 inches at the top and 18 inches at the bottom & yes the bottom cylinder plates are different.
