All - I really hate to keep spamming the group begging for parts, but I think this will be the last time for a while. I am still working on getting my poor HP 89441A analyzer fixed. This beautiful instrument was shipped by a supposedly reputable surplus equipment dealer in a bare cardboard box with no packing material at all. Amazingly, it seems to have survived electronically and most of the mechanical damage is either cosmetic or repairable. Unfortunately, this cannot be said for the front die-cast frame of the RF unit which is literally shattered. A bunch of little bits of it were rattling around in the bottom of the box. After quite a bit of research I have determined that it is originally HP / Agilent P/N 5021-8405. This is a front frame identical to this one EXCEPT that it is 7" tall rather than 8.5":
The part I am looking for is painted off-white rather than being the older metallic silver grey color.
Aside from the 89441A, this part was also used in the HP 8753C VNA, the 8644B, 8664A, and 8665B signal generators, and numerous others. According to Keysight Find-A-Part that list includes:
