Anyone recognise this aircraft instument

Looks like the ASI in the SAAF Museum’s Avro Shackleton MR3 1722. If anyone is interested I will arrange close-up images of the panel?

Not grasshopper – it no have instruments!

Not Vampire, caliberation is to low!

Re Instrument

Thanks for all your help lads, i managed to get in touch with the guy who gave me this and he thinks it was out of a vampire jet, do you think this is possible. Thanks

This is a very common British instrument, after the war all ASI’s became knots as opposed to MPH. Max speed shown on this instrument is 490mph which therefore negates any gliders. I have a number of pilots notes for the above aircraft I mentioned in the last post and all were fitted with this ASI.

The asi in our seafire vp441 is almost identical, 50 to 490 knots.

I do not think this is an ASI. Looking at the scale and calibration I think it has a double-revolution :confused: giving a range of 5 to 49kts. Because the low-end speed is so low I think it could be a marine instrument for a high-speed launch. The Serial number seems indicates that it was made in 1949.
Food for thought and I may be totally wrong. 😡

Absent savings….always a concern…… It’s in Knots vs. the % Mach, I was familiar with ( a second indicator, common to USAF Aircraft)…so I concur with the above…..any “green”, “Yellow” or VNE “Red-lines” (USAF Practice) it would be hard to tell where (If Ever) it was fitted to a particular airframe………yes, even “Back-Then”….maximum effort at “Commonalty” resulted in significant cost reductions qand an effort was made to produce “Common Instruments” that would be labelled at the production, or field level by fitters….

Calibrated in knots rather than MPH and does not appear appear to indicate at values “X 10”, so am I very far adrift to suggest that it was intended for a VERY slow flying aircraft? Would this be an ASI from an early Glider, such as the Dagling or as known in the ATC a ‘Grasshopper’? */ducks and runs away, ahead of inevitable mirth and dirision /*

Ron,
Basically as you know its an airpseed indicator, standard fit to a number of aircraft and not made for any specific type. If I new the serial numbers on the face I may be in a better position to tell you the year of manufacture. On the face of it it looks post war, types of aircraft I would expect this to be fitted too, due to the speed caliberation are psot war transport aircraft. The following are examples of where you would find this type of ASI, Blackburn Beverly, Vickers Varisty, Armstrong Whitworth Argosy, Percival Pembroke, Sea Prince etc. Hope this helps in some way.
