You could check with a PAI dealer for a cylinder or a rebuild kit.

Is it like the old air shutter cylinder on my B?

It basically has a rubber cup seal that is held onto a rod with a small nut/washer.  I was able to find a matching new cup seal and rebuild mine.  Works great, no leaks.

If you run out of option you can send it to me as there is an older gent whom will repair it with pretty quick turn around. I've had him do a couple for B series and one R and they don't leak. In the meantime pull the rubber boot back and get some WD-40 into the area to saturate the seals. Older ones were leather and took to this well.

I found my post from working on my cylinder.  Though I didn't post the part number for the cup seal.  I found one without the hole, but that was easy enough to punch out.

If you get it apart, take the rubber with you to match it at a Industrial Rubber Company. That is what I did.
