Anyone have in their parts 'stash' a 1-30pF glass trimmer cap with a 0.25" dia mounting hole. This will be used for repairing a HP10811 osc.

I don't have a direct replacement, but I do have a few (used, carefully salvaged) Johanson 5501 air variables. The data sheet is at

so you can verify suitability for your oscillator. It's a 1-20 pf unit, not quite the 1-30 pf range that you asked for, but with a few pf in parallel, might work if you can't find a better replacement.
In this oscillator, the tempco might be critical, and the data sheet doesn't spec for the 5501 unit.
Email me if you think you might be able to use it.
