Tapered thread DIN valve?

[EastcoastdiverLLC]

I have a pair of steel 72s circa 1960 with archaic valves that I would like to replace with DIN compatible valves, however, they have tapered threads. Anyone know of a source for tapered thread DIN valves?

I know this is an old thread, but here is a link to a company that sells these valves new.
