If the below info helps,
Here is the info that is stamped into this tank, I have no clue what it means etc,
if you can understand what the below info means, can you inform me, what it means,
it would be greatly appreciated. I am new to this stuff and AR's etc.
Top line = DOT - 3 (triangle?) L- 1800- P846120 . . M4625
Bottom line = TC - 3 ALM - 12 (triangle?) - 11 C 16 - 09 OZ CO2
The spelling in these marks ( ?) is my best quess, as these stamping are very hard to read,
and filled with paint etc.
