Todays sunday market finds..help with i.d.

Hello all!

I found and purchased these instruments today while at the local market.

Can anybody give any possible aircraft types that these could have been used in?

The first is a Sperry Attitude Director Type 2.

It has the following on the data plate:

Code: 226601-0100
Ref: 6tj/1095986
Ser: L 151/C

There are various service stamps(?) with dates from 1971-72.

The second is a Fuel air ratio instrument.

The data plate reads:

Cambridge instruments co inc.

Instrument no: 020977
Part no: 10293
Type: S-IFR
D.C.Volts: 12
Eng,Mfr: P&W
Eng Type: S3H1
Octane Rating: 87

2 pin socket on the rear,and adjuster screw on the front still works.

So..any idea of possible aircraft types?
All information welcome!

Regards,

Ben.
