21AXP22 reliability?

[SwizzyMan]

My 21ax is a colorama rebuild from '62. The emissions are very strong and it performs great. It's a tough one having survived the 1200 mile trip from mass through multiple potholes and frigid weather. I attribute it's long life to the conditions I have in my room. I run a dehumidifier and keep my room at a constant 72 degrees. The only thing that scares me is that the damn evacuation nipple is one of those copper ones that have been known to leak rarely.
