Sounds like that guage is out of a Longranger. We had to do a quick replacement out of the field in our B3. We took the guage out of the L1. the numbers matched from the book.
Although we changed out the guage again at the first chance we got.
The guage was only missing the yellow between 50 and 60%. I have not seen one with a yellow from 85 to 90%??
