Univair Flottorp 26” Prop Need Identification

[The Aviator]

I came across a Univair Flottorp 26” propeller with red tips and the only markings are the letters UA on it. It has 4 bolt holes. I’m assuming it’s for a drone? Like to know what year if possible. No serial numbers. It has the Univair Flottorp branding decal on each Blade. Doesn’t look used at all.

I think your assumptions are correct, and I don't know any way of identifying it any further or even knowing when it was manufactured. I do think that many of these were considered surplus in the 1950s and 60s, so I would guess that the "likely" manufacture date would be in the 1940s - just a guess, however.
