Nope, the K40 and KR40 where opposed twins, the alternate twin did not get made until 1940 with the K50 and KR55 model.
I’ve seen a KR40 run on a small period correct hydro. Neat to see them go. Not scorchingly fast, but fun all the same.
I’m pretty sure Hubble did not make anything for the KR40, it was obsolete by then. Lots of stuff for the KR55 though.
