I've come across this Kollsman Yaw Indicator, and can't for the life of me identify any aircraft that might have used this. Measures 3.25 inches diameter, likely 1950's-era military use IMHO. Any ideas?

Interesting! Over 170 views and no clues or comments about possible aircraft that may have used this?

Here's additional info:
The Yaw indicator most likely came from an aircraft of the US military because it was acquired in bulk purchases of instruments liquidated during US air base (USN, USAF) closures during the 1970's-80's.

I was trying to figure out why the need for a yaw instrument. Two scenarios come to mind; one is bombing, especially toss bombing and the other application might be where yaw is critical for some safety of flight concern like too much yaw at a given speed might cause some structural damage or failure. The lack of increments or warning ranges seems to eliminate the safety of flight theory.

Back to bomb release. Yaw during bomb release is a bad thing for accuracy especially in bomb tossing. Maybe this instrument was used in bomb tss aircraft. I looked on the interweb for B-57, B-47 with not much luck.

How about yaw indications for some early B-52 crossing landing gear application?

Sorry, I struck out.

Doesn't say yaw at all. Number 42, lateral error?

Bingo! The old Lateral Error Meter, of course !!! (USAF couldn't just call it the Yaw Indicator)
You win the prize Taigh! I see that the photo is from the B-52 B model, that's helpful to know.

And Darn it, a fellow just purchased it... probably worth 3x the price! Lucky dude!
