There was a CRT retrofit kit that Agilent came up with that replaced the graticuled CRT with a CRT w/o a graticulean .? 5 of the boards were changed where the XYZ amps were and the new boards generated an electronic graticule.? It looks like someone had a newer version CRT that went bad and replaced it with an older CRT that was handy.

The newer CRTs were also used in the last versions of the 8566Bs also but with a different set of replacement boards.

I think you may have a hybrid made up of some A and B parts. I have no idea how that could be. Is the "CRT graticule" perhaps on the green filter glass insted of the CRT glass?
