Propeller identifcation

Deepforest · Apr 27, 2025

Hello everyone!
I´m new here and Just bought a very nice propeller blade, presumably from a Catalina?? I don´t know!
The blade is aluminium, 154 cm long overall and 24 cm wide.
The markings I found is VP1-103/2 and inside an oval it seems like H54?The other one is 51-A918 and inside an oval N50.
There is numbers from 33 to 47 on the brass gear. The value of it would be nice.(If I paid to much)

The PBY Catalina used a 6105A-12 model blade as a counter weight type, or 6353A-12 as a Hydromatic type, both with a 12 foot diameter. The brass/bronze bushing in the blade bore is for a counterweight type blade.
The 154 cm length is about 5 feet, so would be about a 10 foot 6 diameter, which does matcha PBY.
The other numbers shown are not related to the blade model number.

If I understand correct, and what I found online, mine is a Hamilton standard counterweight model blade probably from a Catalina.
I also read that Counterweight model blade came 1930, and the better Hydromatic type blade came 1937.
What year can my propeller be from? -40, -50, -60 or later? And again. Value would be nice to know.
