WASP 1340 Data

Can or does anyone have data for the early Wasps (420-500HP).
Of all the manuals I have found, the H1 (600HP) was the first to have any power charts. All the early manuals are void of takeoff, climb, and cruise
power (RPM-MP). The H1 manual shows up to 33″ on T.O., but not sure this would translate to the early B thru E models.
Thanks.
