Changing a cylinder gauge on a Morini

[tufty]

My cylinders are about to fall foul of the ISSF 10 year rule,but a friend has given me 2 cylinders that he doesn't use,but one has a broken gauge,how easy is it to swap a gauge from one of my old cylinders?

Hello I would like to remove the gauge to see if I can replace any seals in it that's causing it to leak.
Does anyone know how to remove the gauge ?

I have replaced the cup seal already, but I'm not sure how to remove the gauge.
Also, it been a while since my last post some 10-12 years ago.

Supposedly it's not too difficult if you can find the correct spanner. A fellow coach was talking to Buck (Pilkguns top air-gunsmith) about this at the US National Collegiate Championships. Here's a photo of the spanner he uses:



The "30 32" is presumably the outer diameter range for the spanner. The Morini cylinders are 30 mm in diameter. The pin needs to fit in a 4 mm hole. In theory, this one should work:

Either make one from 1/4" x 2" strip and a drill shank or look on the net.

Yes, I have removed the black aluminum cap over the gauge end.

Now, how to remove the gauge off of the AT ?
I tried turning and pulling and haven't been able to remove it.
