A rotten tube

Today was Parker 51 day at the repair bench. Opened up a mid-1950s Aerometric, first pulling off the filler housing and then the sac, revealing the sterling silver breather tube. At first glance the tube looked as if it might still be serviceable, but its floppiness called for a closer look. Click on the image above and you'll see what I saw. Rather spectacularly corroded (the right side is the one originally stuck into the feed), so it was promptly replaced with a new stainless steel unit.
