That one may be hard. There were a number of propellers manufactured under military contracts that used that designation (year, followed by "K", followed by a number), but the all of the numbers I've ever seen have been 5 digits, not four, and those go back to 1942 so I don't think it's just an earlier number.

There is at least one documented example of a two-digit year followed by “K” then followed by a four digit number (44K9705, please refer to http://www.modernwoodenpropellers.co...h_military.htm). I have found in very many instances concerning WW-II aircraft and parts other than wooden propellers an “X” precedes a valid number in cases where one or some examples were submitted to the military for approval. The "X" indicating experimental. If approved the “X” was subsequently removed. Your prop may be one of those submitted for approval but I cannot document that as fact. I have no clue on who manufactured it.

I have a wooden propeller with the same number:
L-U.S.A.DRG.NO.X43K9493. I'd love go get some information about it.
Thanks.

There has been a previous thread on the subject of this design number:
http://woodenpropeller.com/forumvB/showthread.php?t=408

What is certain is that the propeller was designed for use with a Wright Whirlwind R-975-E3 engine; all I can add to that is the observation that in every application that I can find, the Whirlwind was used with a metal propeller.

For a wooden propeller to be used on this engine as late as 1943, suggests a specialist application and that makes me think that the suggestion made in the linked thread may be correct, i.e. that this design of propeller was used when converting Avro Ansons to Mk lV specification.
