I have an extra Acme 1273 for sale. I sold my 2008 B52 23V earlier this year and this was my backup prop. It's in it's box and shrink-wrapped, I could ship it wherever but I'd prefer a local pickup as I don't know how much shipping would be. Prop is in San Francisco. Paid $500 for this and thankfully never needed it. Asking $300 o.b.o
Details on the prop:
ACME 1273 4 Blade 14.5" x 14.25" Propeller
Rotation: Left Hand
Shaft: 1 1/8"
