Thanks everyone. In the middle of cleaning the smaller gauges. The larger ones also need repair, blasting, and painting; so considering having them done. We'll see.
Noticed that the smaller gauges have an inside seal (looks like dried, cracked, cork) You can buy the rubber outside gaskets (and replacement small leather oil gasket), but haven't seen these gaskets for sale. Guess I could use some flexible silicone caulking.
Any thoughts?
Thx.
Will
