It isn’t supposed to be bent and the thin rod should be longer; how much longer I don’t know as it was cut-off before I got it. Overall length is about 200mm with the rod being about 8mm in diameter.
It is very well made; the spring fits over the larger diameter and there was a two-part metal sleeve that fitted over that. The alloy cone was attached (with a very fine screw thread) to one of the sleeve parts and this slid inside the other sleeve part which was attached to the main body (with another fine screw thread).
The main body is hollow and open at the threaded end (although it is packed with clay) and the thin rod (which is solid) seems to be attached to a ‘piston’ inside the main body.
My thoughts are that it is a hydraulic-ram, although there are no inlets/outlets and no trace of oil, but for what? And why the protective sleeve over the rod?
Any ideas?

Just a thought, and I may be well off the mark with this.
How about one of the pneumatically operated, spring-returned SRCO rams from Packard-Merlined Lancs?

Supercharger ram? Looks a bit like this http://www.ebay.co.uk/itm/190654607037
especially the cone on the end

The Spring-loaded protective sleeve that covered the rod of the ram would seem to indicate that it was intended to work in an environment that was dusty or gritty (the sleeve wouldn’t have kept fluid in or out) so that may indicate that undercarriage is the right area (for grass runways).

Also, that part looks like it is to big for the hot and cold air intake ram as well..

What picture shows the radiator shutter ram? :confused:

No that pic shows the radiator shutter ram.. nice idea about the undercarriage downloack ram.

Just a thought, have a look at the downlock mechanism on the undercarriage legs… there are a couple of rams on there, and I don’t have a photo……

Nope, I don’t think it is that one. Excellent photograph by the way.
I was looking at some photographs on this forum of the Duxford AVRO York and I think you can see the radiator shutter ram in those; it looks more like the slow-running cut-off ram that the mystery one. I’m beginning to think it may be hydraulic after all.

If the slow running cut off ram is the one which is located on the port lower side of the engine and attached to the lower strut of the engine mount, then I’d say no. (seen here tie-wrapped to the lower edge of the firewall). That said, its plausible that earlier marks of engine would have a different type of ram…. it appears to be a similar size. How I wish I had taken photos before it was pulled to bits.

I was thinking the same thing or a slow running cutoff ram?
