Help ID Small Steel Prop Blade

[James101]

Blade seems to be hollow steel. Around 50" long. Lots of numbers on it but I can't find any information on them.

AC-41-126?51 The ? is possibly a 6 or 8, hard to read.

Information received:

"With regard to the subject it would I think have been helpful to have a photograph of the underside of the blade base showing the numbering in true context. I wonder if there are some missing hyphens in the text.

Nevertheless, it seems to me this is a Curtiss blade for a prop of around 8ft 6ins diameter or thereabouts. My guess is a 2 blade prop for a trainer or similar.

As always, I hope this helps."
