Hey @Tony Bird - kind of hi-jacking your thread here but I found a pretty cool video where I think you modified a Mamod Cylinder to have "O-Rings"?  I have to say that is pretty cool "upgrade" to their cylinders.

You wouldn't happen to want to sell me one that would fit a late 60s / early 70s Mamod SR1a Steamroller?  My cylinder isn't like the ones they sell today, its slightly smaller.  I have a thread here where I chat about it, Another Gift: Mamod Steamroller SR1a
