SEMI-OFFTOPIC: where can I buy HP 1630 data probes

[Anubis]

I have an HP 1630 logic analyzer at home. The 10271A and 10272A probes
are worn and some are damaged. I have been scouring ebay looking for
replacements but havent found any.

Given the age of the product I doubt I would be able to get any from the
manufacturer.

Any ideas?
Thanks in advance
