I found a local guy that has a tank for sale.. and I have read a few other sites about identifying owner tank to rental tanks..

I kinda get the no name on neck is one indication its owner tank and something about companies that were bought out and no longer in business may have the name stamped on the next BUT may still be legally owner bottles..

So before I purchase this tank, can anyone tell me if the numbers stamped on the tank indicate otherwise?

Here are pics of the stamps visible on the tank, what do they mean and is it ok to buy..(keeping in mind that there is no name or writing of any sort on the neck)

thank you
