Help! - Wooden prop - any info?
I have a wooden prop, which has been in my family for many years. I know
very little about it. Can anyone help? It has the following information on it : Admiralty Design (Transfer) TREPACO Trevor Page & Co Ltd (Transfer) Norwich Eng The following info is all stamped in the wood. 448 (Suspect this is a serial number) AD545RH D2520 P1580 90HPCURTIS Two stampings which say AOP & ADP (Not very clear) 99.5 inch x 3.75 inch thick, blade approx 9.5inch max width Central boss 7.75 inch diameter Weight 20lb 6 holes for bolts, central hole approx 2.625 inch I'd love to know what aircraft it may be from, and whether the family info that it dates from the 2nd World War is correct, and what sort of value it has. It seems to be in pretty good condition. Thanks in advance. LB |

It seems to be in pretty good condition. Thanks in advance. LB It is a Curtiss OX-5 (US made) prop. Probably dates from post WWI. D and P are pitch and diameter in mm. OX-5s were used on Jennys during WWI and any number of post WWI planes through the '20s into the early 30's. The engines were 90hp water cooled V-8s and were surplused after the war for next to nothing. They were not known for reliability but then none of the engines at the time were known for reliability. They had a unique single pushrod that operated both the intake and exhaust valves. A number of the engines are still being flown. Worth a couple of hundred dollars US if in good condition. They are fairly common. Please don't make a clock out of it. Keep it original. |
