Note that the cylinder in the patent has seven chambers. S&W had originally considered a longer ".32 Special" for the K-Frame. It would have been close to the .32 H&R Magnum in case length with a longer ogival round nose projectile.
Jinks mentioned the 7-shot .32 cylinder idea in passing, and I will have to check for the source on the extra-long .32 cartridge.
Found it on Pg 312 of Suydam's book. Case length: 1.113". COAL: 1.542".
