HP plastic slide switch knob - UK Vintage Radio Repair and Restoration Discussion Forum

I'm looking for one of the HP slide switches (and its spring) to replace one broken in a generator (8672A). It's the short type, not the longer one used in the 8640. Photos show an unbroken one for comparison and the broken one and its contacts.

I thought I'd buy a scrap pulse generator and extract one; but it seems that I cannot bear not to fix anything (inkjet printers excepted) that says HP on it, so this plan isn't working. I think they were used quite widely e.g. 8620 sweeper, 3762 data generator, 8007, 8012, 8082 pulse generators of the troublesome slide switches era. So asking in case anyone has a really scrap HP specimen (mouse ate wiring) that could help me out.
