I rescued a nice HP 339A distortion analyzer from an e-waste bin at
work, but not before another piece of equipment was dropped in an
sheared off the 400Hz filter button cap, which was lost.? There is
about 1/8 inch of the push-button switch post left inside, behind
the front panel, and the switch stills works fine if poked with a
stick, but looks bad.
Questions:
1. Is there any source for the grey cap nowadays?
2. Could a remaining button cap next to it be pulled straight off
as a sample?
3. Has anyone made a new button from a sample with either epoxy in
a mold or 3D printer?
4. Any other ideas for button cap repair/replacement I'm missing
besides buying another 339A for parts?
Thanks.

*Knobs for 339A's are worse than hens teeth and rocking horse muck!.
If you can mould one or get someone with a 3D printer that will be your
best bet.
Seems such a shame to get one to scrap, they are an excellent unit:-)
As to the Oik who dropped the other gear on it, Lynch him!!!
* I did get a few off a supplier in Canada, Scheer or sounds like that
she there did have a few if you or anyone else can find who that may be
they do advertise on the group sometimes might be worth asking!..
