Wow, thank you CHfather. You just saved me $100 because they look like medical bottles.

I never even considered that I would need a script to get oxygen to fill these, I think these headaches clouded my thinking, haha. Looks like I just need to buy a big welding tank.
Great looking out for me, awesome
I am actually in the automotive industry and have bought oxy/acetylene tanks in the past and have them filled at the local LinWeld without problems, so Im just going to go that route.
Thank you for the links! Absolute life/wallet saver!
