Possible Norden bombsight part?

[5thwingmarty]

This was among the parts I was given a number of years ago from the wreckage of one of my uncle's B-17s. Most of the parts I was given I could identify from the numbers stamped in them, but this one remained a question. A friend who was a B-17 flight engineer thought it might be a servo for some part of the auto-pilot system, but I just saw an image elsewhere of what was identified as the gyro for a Norden bombsight, and it was very similar to this. Unfortunately I only have this one image of the part, which is about 4" across if I remember correctly.

 

One of the other parts I was given was the remains of the mount for the bombsight, so I know they had the bombsight at some point.

 

Any bombsight experts out there who can tell just from this image?

I was able to connect with wistarmo who works on Nordens and he confirms it looks like a gyro from a bombsight, although he says they are supposed to be painted black.

Here it is. It is the horizontal gyro from a Norden bombsight sighthead. I have removed the bottom gyro bearing cover.

Thank you for posting this photo. That is clearly the same part and its nice to see it from the same angle as my photo.
