I have an original Grimes rotating beacon light.
The part no is 46-0101-15-12
Grimes MFG Co.
This information is on the light.
I had it as a spare part for my other airplane, which is sold now, so I don't need it anymore.
I want to have $140.00 for it.
You can always ask for more questions or a picture of it. It is in a good state.
