A Paragon 7' 1/2" Prop

[CassieRaef]

The only reason I know it is a "Paragon" is that a small part of the decal was faded that read "Baltimore, Maryland" was on it.
But, can anyone tell me what plane Paragon may have used this 7' 1/2" Wood Prop For? I want to sell on ebay, and know little about it.

Without drawing numbers it's nearly impossible to identify the aircraft, and frequently even with those it's impossible as well.

All I can say is that it looks like it was manufactured in the 20's or later based on its general design and the fact that there are only 6 bolt holes in the hub. Most all of the early (pre-1920) era propellers used hubs that had 8 bolt holes.
