the following late fifties HP equipment is available

Stored in less than ideal conditions, but seem otherwise quite OK.
Feel free to forward to more fitting mailing list / fora.
Not my equipment, my only interest in this is saving these from the scrapheap.
HEWLETT PACKARD TIME INTERVAL UNIT 526B
HEWLETT PACKARD ELECTRONIC COUNTER 524C
HEWLETT PACKARD DIGITAL RECORDER 560A
( Possibly a second HP524(b) , unsure of this )
I will forward email adresses tio the seller, up to you to complete.
He expects to raise some money, unsure if realistic or not.
I think I've made this comment before when this type of equipment has been mentioned
on the list,
but as it's being mentioned again:
The 524C is a tube-based NIXIE-display digital frequency/period/event counter,
the 526B is a plug-in input module for the 524,
and IIRC the 560 is a printing recorder for use with the 524.

In my opinion, it's a reasonable acquisition for a computer museum as an example of
tube-based digital technology from which the 1st generation of computers were built
(seeing as how tube-based computers are a tad difficult to come by these days).
If you're an HP collector, the 520 series was HP's first step into digital
technology.
