Does anyone out there in r.a.s. land know how to get a German Oxygen
cylinder recertified to DOT specifications, and a place to get it done? I
think it is out of date, and I got I with the glider, a DG800B. It appears
to be in good shape-no dings or scratches. It has no DOT cert number on the
neck, and was imported with the glider-factory installed.

Thanks in advance

Find a local place which does cylinder filling, most compressed gas
supply houses and diving equipment service houses can do hydrostatic
testing. e.g Airgas, Praxair, or BOC dealers. This should be done
every five years.

Google search turns up a lot of hits.
