Hi David,toggle quoted messageShow quoted text
That component looks identical to a device on my 546. It's a light guide
that channels light from the two graticule illumination bulbs above the
screen into the side of the tube face which, on my 546, has the graticule
lines built in.
I wonder if your scope has had a tube change for one that doesn't have the
built-in graticule lines in the past, or the plexiglass components have
been swapped with a scope with internal graticule lines?
Hello, Thank you for your assistance Kevin & Chuck, I have learnt a lot
