Hmm ...

Maybe off base here, but 753 is really thin stuff - but there was French tubing drawn in extremely light guages long long ago, that as I understand, was never available in the imperial sizes (on thin ice here).

So, if Reynolds comes out with a new alloy that lends itself to extremely thin guages, then the dies and mandrels it needs to make the stuff might have been left over from the days when 531 was drawn in metric diameters for the French market.

Does this make sense?
