Ultimately no, I think. I'm just trying to find out if there was a historical difference between the two vessel classes in regards to the propulsion design. They look similar and may be the same ship for all intents and purposes but they have very different roles...
I figure maybe the PCE required "speed props" while the Admirable class minesweeper needed better power at lower revs for its mission and role?
The USS Hazard (AM-240) which was originally buried up to the waterline as a museum ship, was refloated by flooding in 2012 and when the waters receded she settled again and exposed most of the hull to include the props which are also 4-blade. Of course this proves nothing so...Pffft! Who knows?
Anyway, back to your build, sorry for the diversion.
