Anyone can post the two o three rows of info on your 10lbs bottles, ej. DOT3ALM1800

I would like to know which years and who fabricated them..?

Any one knows if the bottles are the same as the ones used for fire extinguisher.?

I have 10 brand new 10lbs fire extinghuisher with luxfer bottles and want to change just valves to use as spare bottle. My bottles were fabricated on 02-2003
