I would like to thank everyone in advance!

I attached 4 pictures.

Here is what can be identified off the top of the tank. (My comments are in parenthesis)

Druckluft (Compressed Air) TG (???)

F. 150 (?????) P.225 (BAR ???)
G.17.8 (weight kg?) L. 15 (Liters?)

5.91 Manufacture Symbol/Stamp 93

Would like to know all the following if possible
1) Manufacture
2) Size
3) Pressure
4) Will I have trouble filling these at any dive shop after hydro and visual.
4) Am I missing anything?

I plan to take all this information to my LDS and find out all of the following
1) Will they hydro, visually inspect and fill these tanks?
2) How much will this all cost?

Then I can determine if they are worth purchasing.

Thanks again,
