Hard to tell if they mean the nbl warship 43's or the original hst 43's.
Either way we already have both though there will be detail differences I'm sure.
Could also mean HST Prototype possibly?
We have the recent, and rather nice 42 from Farish, but like you say most of the differences between that and the original 43 appear the be down to the internal mechanicals.
Just goes to show how challenging it is going to be bringing this data together, but since the votes were by way of PM, I guess Newportnobby could possibly go back to the voter to clarify?..
