the sprocket range was 13T-24T and with a double chainwheel total capacity was 15T.
The RD was not designed for the capacity you are expecting of it.

All true. My friend ran a 1/8" 3-speed 13-19-25 cogset on a Sturmey-Archer AW hub, and the bandspring rear derailleur worked like cr@p with it. I did not have much better luck with my 1/8" 4-speed 14-16-18-20 cogset on a S-A hub until I switched to a REAL derailleur (first-generation Campag. GS), which worked like a champ.
