[T3] Metric V SAE...

Hi there

< I've a feeling I've seen that explanation for the inch sizing of hydraulic cylinders/seals - they started off in the USA>

The explanation given me by an old-time Porsche wrench was that the tooling for these rubber parts in post WWII was unavailable...so they used what they could get from the US/UK.  It stuck.
Another example of this was the 6v electric fuel pumps on the early 356 Carreras...made in the USA by Autopulse.
Domestic German production hadn't yet caught up.
Hope this helps.
Best regards,
FE Meek
