Is there a kit to rebuild this?
Ayuh,.... Unpopular cylinders, from a long, Long time ago,....
I've never seen a "Kit" for 'em,.....
But,....
I've run across plenty of old cylinders that weren't popular, 'n leaked,...
If ya pull the cylinder apart, 'n can Id the o-rings, 'n seals to the .001",.....
These folks will sell ya
All the parts, 'n pieces ya need,...
