Hello,
my boyfriend purchased these two instruments today,and he needs some help to find out the type of aircraft they have come from.

The first is a Fuel Air Ratio gauge.
He knows it hs come from a Pratt and Whitney S3H1 powered aircraft.
He as done a little bit of research so far with these as possible aircraft types.

Texan/Harvard,BT-13/14,Noorduyn Norseman,and Lockheed Electra.
Anybody got any cockpit views?



The second Instrument is a Sperry Attitude Director Type 2.
So Far he has found it is used in the Trident airliner,but are there any other types?



My boyfriend would love to know more about these instruments.

Many Regards,
Emma.

Well, I have to admit, this is a hard one, since many aircraft could have used those same exact types of guages. Of course, I guess you can try to contact the manufactures (if they are still around), and then use the numbers (serial, code, etc.) to get some idea on what type of plane those instruments were on first.

Hello Emma
The second instrument is very familiar to me albeit a long time ago.
The attitude indicator is indeed that fitted to the Trident aircraft and is part of the Smith's Flight Control System that was standard on the BEA/British Airways aircraft (Trident 1C, 2E and 3B). I believe it was in fact manufactured by Smiths Instruments in Cheltenham, not Sperry.
As far as other aircraft using the instument, I believe that the BAC 111-500 delivered to BEA in the late 1960's (G-AVMA-G-AVMR) also had the Smith's Instruments flight display only, but it was connected to a Sperry auto pilot/flight-director control unit. This may be the clue to the origin of your items. The pairing of items from different manufacturers was as a result of a desire by the BEA management at the time for commonality of pilot flight displays between the two fleets and this requirement caused considerable technical difficulties and delays to the introduction of the BAC 111-500 into service with that airline. BEA was the launch cutomer for the larger -500 version of the BAC 111. Other operators of the type specified the more commonly used Collins flight display (and probably autopilot). There was a desire in those days by The Corporations (BEA & BOAC) to use British equipment were possible. The manufacturer of the 111 (British Aircraft Corporation, later British Aerospace) was wise to offer the Collins system because I'm sure it was the availability of this option that helped the relatively good (by British standards) sales numbers of the type worldwide.
The last operator of the ex-BEA aeroplanes was European Air Charter at Bournemouth. They bought the entire fleet and spares holding from British Airways in the early 1990's when the fleet was phased out. They only recently stopped flying the last of them and are in the process of breaking them up, presumably at Bournemouth. I suspect that you boyfriend's items may have come from this source.
I hope this of interest and help.
Dave

Thank you for all the information,chaps.

My partner thinks it came from a long retired trident as the last dates show 1972 on the attitude indicator.

again thanks for the insight and information!

Emma.
