Old O2 cylinder

I hear ya! I love the 1075. Taste the food, not the fuel. I can fix propane leaks and not smell like diesel the rest of the day. I can’t fix your bbq tank. Just MC330/331. If the hazmat is dripppin’ don’t be trippin’.

Propane is safer than acetylene but what I don't understand is why places selling/filling don't give a safe handling and use brochure or booklet with it. It is literally boiling at below -40 and if leaks will cause severe burns. Tanks are filled to 80% capacity to allow for expansion in the heat but there should still be warnings to keep it away from sources of heat like furnaces or heaters. Click to expand... I've had to set propane tanks on a campfire to thaw them so they'd work. Barely will flow at -30* even. Shake hands with danggger. Years ago my Dad set some frozen rattle cans in the stove in the garage to warm up. Surprisingly didn't make that much mess aside from his pants. Was brown paint and the one that blew it's load all over his pants.

I've always thought that gas cylinders are a great business model. What other asset gives a regular monthly income for so many years with so little maintenance?

No, I get mine from a website gas supplier. My personal bottle, and the bottle at our farm are both a really deep blue, not the same as the Thoroughbred blue from TSC

I wonder how many times over all these years has this tank been refilled ?

That's either a 1917 (1st retest date) or a 1912 cylinder! Probably been filled thousands maybe 10's of thousands of times.

I had posted this one here quite some time ago. Wish I could've kept it, but I didn't. It also dates back to 1917.

I don't believe the swastika/window pane has anything to do with the third reich because it usually seems to be found on cylinders made in the teens, long before they existed. Also these cylinders have ICC numbers, that stands for Interstate Commerce Commission forerunner of the DOT which is a USA organization. Euro cylinders would probably have a different spec number. I suspect it is a maker's stamp, maybe Linde trademark or something. Here is mine, seen on a job walk once.

I'm sure lots of cylinders were made in Germany. Maybe the swastika was put on to keep the cylinders in Germany?? Perhaps the swastika was stamped on cylinders so they would be exclusively used for the war effort??

If they were made in Germany then they would not say ICC on them.

Technically to be a true Third Reich item---the cylinders would have been in a date range of March 1933 to May 1945. Anything before 1933 or after 1945 is subject to doubt.

With the millions of cylinders out there it's not unreasonable that some cylinders made outside of the US made it to N America. Perhaps the 3rd Reich comandered cylinders for the war effort and stamped them with a swastika? Would need to look at some cylinders with the swastika.

If they did so, they would have had to re-stamp them ICC somehow. I have never seen any evidence of that.

I can't see a swastika as a random stamp put on cylinders. There's only a few companies that seperate air to get pure oxygen and they supply O2 all over the world. Perhaps all cylinders are/were stamped to meet international standards so they could be used world wide. I think a 1943 swastika cylinder was posted on the welding web years ago but nobody paid attention to anything other than the swastika.

Messer Industrial in Germany used the Swastika on their export bottles. I see that Linde and Messer have merged. Messer started manufacturing tanks at the turn of the century.

Did the US manufacture bottles before WWII?
