Are there any other numbers? Ending '55' does not make sense on the DH blade numbering system. You'll know that it's a 6,000 series blade as per Beaufighter, but blade numbers themselves go up in 3's either from zero or 1 depending on whether 3 or 4 blade applications. The last two digits being 15, 16, 65 or 66 would make sense, but not 55 - UNLESS this is a left-hand application with blades cropped four feet six inches, making them very paddly and 10' 6" diameter.

Correction, 10ft diameter - and very odd looking. Are there no other 56xxx numbers?

Brigand? Only I would expect to see a 'T' suffix on the end, for 'telescoped'.

That's a Hamilton Standard Shank. I was thinking de Havilland!

Of course if it's American you are absolutely right.
