Yes your Cylinder Top Lid [jar lid] does appear to be a G&B.
Cast Top w/ Globe holder does look similar to the G&B 67 Top Casting [I've never had a 67].
But there are Several things Wrong in that link that
"They Claim to be Historic Correct" for the T-178.
[Picture #17 shows the pump unit & base for a WAYNE 615]
The cyl. base casting has 3 pipe frame & Base has 2 inner round holes that were used to support the pump mech, not frame mounts.
...also a 24 inch globe fits it when assembled
Say what? Ya lost me.
What does the Cylinder dia. meas. Outside to Outside & Heigth?
