This last weekend I was shown what appears to be a vintage aircraft propeller. The person who holds it got it from another chap who claims it is a propeller off ‘a World War 1 Avro’ – presumably a 504.
I took some measurements and photographs of this item, which is currently mounted on a wall. It was apparently found underwater, so all markings have been erased by the process of time – probably by sand abrasion. The measurements (I only had a metric tape with me) are
Overall length tip to tip 2730mm
Diameter of hub 200mm
Thickness of hub 145mm
Width of blade at widest point 230mm
There are 8 bolts in the hub, and 6 laminations of timber in the blades.



The item was said to be found at Tauranga Bay, in New Zealand’s Northland area – see map below. This could possibly make sense for a 504K relic, as there are two potential sources:
– The New Zealand Flying School (Walsh Brothers & Dexter) operated 504L seaplanes in the Northland area in the time period 1920 – 1924.
– Les Brake, an itinerant joyriding pilot operated an ex-NZPAF 504K off beaches in Northland 1931 – 1933.
Any identification/feedback on the above welcome.

Looks like later 504 to me – I have two early types but am pretty sure that you’re right – try also www.avro504.org
Cheers

As already stated.

We need to know what is stamped on the side of the hub. There should be some writing and numbers. Then should then be able to identify what it is from.
