Hey Neil 

thanks for the reply - unfortunately the shop I had rebuilding the cylinder scrapped it and I don’t have it to measure from - but thanks ! 

 Can anyone help me specify what pneumatic cylinder goes with the bull hammer 125.  I bought this machine in 2002 and it has been a good machine however the cylinder has been destroyed and scrapped before I could get any specifications off of it. If anyone has one that they would be kind enough to take pictures or pull a few measurements on I would be eternally grateful.  Or if anyone can help me specify a new and different cylinder for it that would be great too. I’m aware of the problems with Bull and Phoenix and I am relatively sympathetic to their original builders . Thanks a million
