My bad. You're right. I was working from memory. FWIW, Wikipedia claims that initial work on APDS was by a French company, but later the designers were evacuated to the UK and completed the work there.

As for APCR/Panzergranate 40, while the Germans were one of the first nations to develop it, shortages of tungsten meant they had to discontinue making it.
