Look at the AN-5736 series and see if that matches the hole pattern. I think it's the large diameter series, also known as a C-7.
PossiblyWurger Wojtek. I would need to know the key dimensions and when these were first produced to see if these are options.
EDIT. One thing I see is that the raised portion behind the adjustment knob is the wrong shape.
No Joe, that is similar to the wartime configuration circled in the first panel pic I posted above. The calibration knob on yours is on the bottom whereas the one I need is at the 7 o'clock position.Found this - again, a shot in the dark

The indicator unit I'm looking for is bolted onto the instrument panel.where would it sit in the cockpit?
Yes - seen that, also seen how the artificial horizon had the cut out to the right, thought there might be an overlay when comparing the two photographsNo Joe, that is similar to the wartime configuration circled in the first panel pic I posted above. The calibration knob on yours is on the bottom whereas the one I need is at the 7 o'clock position.
GotchaThe indicator unit I'm looking for is bolted onto the instrument panel.
Yes. It would. But in what place. Werent the instruments grouped to function.,?No Joe, that is similar to the wartime configuration circled in the first panel pic I posted above. The calibration knob on yours is on the bottom whereas the one I need is at the 7 o'clock position.

OK. Look at the first panel picture I posted. See the yellow circle? Now look at the second panel picture. See the big hole where the yellow circle in the first picture is? Thats where the mystery unit goes.Yes. It would. But in what place. Werent the instruments grouped to function.,?
Yes. Artificial horizon and directional gyro usually close to the center. VSI, airspeed indicator, turn and back indicator usually off to the one side. Engine instruments usually on the right side of the panel looking forward, some aircraft like the Mosquito had them on the left.Yes. It would. But in what place. Werent the instruments grouped to function.,?
OK - gotcha now!OK, I guess I'm not explaining this very well so I will try again. Yes Joe the picture you just posted shows a typical wartime Mosquito Blind Flying Panel with the small Directional Gyro with the knob at the bottom. It's probably an F.B. VI Mosquito. The aircraft we are restoring has a MODIFIED Blind Flying Panel as pictured here with the cut-out for a more modern (ca. 1960) Directional Gyro Indicator shown in the red circle.

I have a good handle on what instruments I need to insert into the other 5 cut-outs (ASI at top left, Artificial Horizon at top center, Rate of Climb indicator at top right, Altimeter at bottom left and Turn and Bank indictor at bottom right) but I need to find an American Directional Gyro Indicator that will fit into the large circled cut-out with a knob at the 7-o'clock position. We're NOT restoring our Mosquito to a wartime machine but a rather unique civilian bird.
OK, now the brain is engaged, I don't know why I glossed over that part of the equipment listYep. That's how I know they had a Sperry C-2 installed in 1957 (see the excerpt from the Equipment List in the 1st post). Unfortunately, the C-2 dimensions are not consistent with the larger cutout and screw pattern so I suspect they installed something newer after 1957. Unfortunately records of W&B reports and Equipment Lists stop in 1957 but our aircraft and others continued in service until the early 60s so that's why I'm looking for help. I agree that if we had later documents then that would make things clearer. I'm pursuing another source for those docs if they exist.
