I picked these two up last month, I’m guessing mid 30s. Did the earlier PL53 model have the riser tube under the control cock ?
This is going to be a hard one to give an accurate answer to. The pictures in the catalogues are not much help. I have been looking into this but I don’t have my notes with me. @Tony Press will have something to add.
I see I’ve been dropped in it by @Anthony... Darren raises an interesting question here, about the presence or absence of a fuel riser on the PLs. Anthony and I have been pondering this question and it’s hard to get an clear picture of what the pattern is (and why). [I note that my EX 93 has a riser, and it’s the only one I’ve seen with the riser]. I think I’ll start a new thread “Does Your PL53 have a riser?” Cheers Tony
The link below shows two of my copper ML., tanks and the small tank has a riser tube and there is more information shown there. 2, Copper ML-tanks. 2 photos Tony Press
