no, its yes'nt
I personally can prove it. But I'm not losing my job over an Internet discussion. There are many cylinders still in circulation from the 1900s.
so you can prove it... but what? what would you have to say to prove it, that would mean you lose your job?
Yes. I have photographic internal proof about those markings and what they are and how we deal with them.
i mean, a bunch of other people have explained it as something along the lines of "the canisters have basically no expiration date, so we still use the ones that used to be used during the second war"
i don't really see how saying that could mean you lose your job (unless there's some shady stuff going on, i guess)
I'm not disagreeing that they are that old. I in fact know that this was at least from 1948.
ok
so you can prove it... but what? what would you have to say to prove it, that would mean you lose your job?
This is not one.
1948 isn't from the 1900s?
Before end of WW2 linde used swastika as company logo on tanks. After WW2 they used the window. Many old tanks had the swastika changed to a window, often very poorly. This is a tank from 55 that never had a swastika stamp, just a window stamp. Lots of poor information about this on the Internet that is mostly just forum posts. People see the window and instantly incorrectly think it's an altered swastika. Look at pictures of other window tanks and you can see they are all done poorly prior to 45 and are clearly altered. Starting in 45 they all look perfect and sharp because they are original window stamps.
I wonder what the window stamp means...
It means Linde. Here is a cylinder from Linde/Union Carbide that was made in 74.
There is literally a "nexair" barcode on the right
That's who refilled the tank and supplied it last. Linde hasn't been around for a long time.
You're kidding right?
Not at all.

I thought Linde went under praxair. I now see it's going strong and the parent of praxair.
