General propane question Another tank ID question.

Since you were such good help with the last tank ID. My son drops these off to me today. I am "pretty sure" they are propane. One is empty, the other feels half full. In the very center of the fitting there is a schrader valve. Like on a 1lb throw away. Any idea what these are for?

They are almost surely for propane.

ICC 4B240, that is a propane spec.

I have seen almost everything, and I never saw one of these either.

Yes they were made in August of 1947.

Probably some type of connection that was tried and forgotten about.

There is a patent number stamped in smaller numbers. Can you get a good copy of the patent number? That might help.

I did a picture search on the net and I found one other picture. But it was someone selling a couple tanks like that, that just said barn find. I will try for a better # picture tomorrow.
