Dave, I’m not positive it was glass. It just appears to be since that is the only part missing. But you’re right, it doesn’t seem practical that glass would be used on something that’s getting moved around all the time. The cylinder may have been taken for parts for another one as well.
Here is a green Quaker State one (that appears to be for a barrel) and I can’t tell if it’s glass or metal in this picture.
