I didn't know where to even begin a search for this one, so I'm just going to ask here.
A guy at work gave me an old steel cylinder that was in his garage when he bought his house. He didn't know if it had any value, but he knew I was a diver and gave it to me. I took it to my LDS today, and nobody had ever seen anything like it. I left it at the shop, so I couldn't get any pictures of it, but you should have seen the home-made valve on that thing.
Anyway, I wonder if anybody here might be able to decipher these markings on it, and tell me what it is.
ICC-3A1300 SPUN (then there's a mark that looks like a letter N with the top right leg crossed like a T, in a circle)
F-404922
C-O-TWO F.E.C.O.
(a mark like Pluto, a P with the leg extended like an L) - 23
6-44
And on the back side:
2 (a mark I couldn't make out in a circle) 61
The neck on this thing is way bigger than a diving cylinder, and the valve had a handle on the top, like a propane tank. It had a brass, apparently home-made adapter on it to fit a yoke valve. The burst disk was under a solid plug, or maybe it had been filled with solder. We took the valve off (wish I had a video camera for that event) and looked inside, and it actually didn't look bad inside. The bottom of the cylinder is inverted, not flat or convex. It's yellow, with faint traces of red here and there.
I know ICC stands for Interstate Commerce Commission, which predates the DOT.
The guys at the shop deduced that it was made for carbon dioxide (thus the C-O-TWO) in June of 1944 (the 6-44) by a company named F.E.C.O. Apparently it was hydro-tested in February of 1961 (the 2(*)61 mark). And it looks like somebody rigged this non-diving cylinder up for SCUBA diving by brazing together a makeshift valve adapter.
I left the cylinder at the shop for now. If this post generates any interest, maybe I'll take my camera and get a picture.
