Hi, I obtained this recently from an internet auction, shaped very much as a propeller and very heavy 17kg. It’s laminated as a propeller would be but just wondered if any one had any ideas as to what it is from? I wondered if the written style of letters and numbers could denote a particular country or is the style of stencilling pretty much universal? Thanks in advance if any help or suggestions.

Many Thanks for the information Nicko, it’s appreciated.

Neatly sawn off! I think there is little doubt it is from a test club. They will be very heavy to absorb the power of the engines being tested which matches with your 17 kg. I don’t know any of the test club manufacturers, but I understand that it tends to be a specialised part of the industry, so only a small number of manufacturers.
I have seen a font that looks like that before, but I’m not sure if the font means much: apart from the fact that these test clubs tend to be very robust and therefore last in use for decades, the stencil machines tend to last many decades. I have seen several pairs of 1/2″ and 1″ stencil machines here in Australia that date back to the fifties, that are still in use. Lucky if you were in the right place at the right time and could pick up a pair being disposed of by a large defence contractor!

Hi Nicko, Many Thanks for your reply. As requested attached are photos from the other end. The leading edge protection is a metal type either copper or brass.

Hi FLY.BUY. Can you provide a photo of the opposite end? If it is sawn off then I imagine that this is from an engine test club.
What do you think the leading edge protection is made from?
Cheers.
