Search manual for HP K02-5060A power supply

[AlcidePiR2]

Dear All,

The HP K02-5060A power supply was used with the HP 5061A Cesium clock to make the first flying experiments with Atomic Cesium clocks  in 1964 allowing clock synchronisation over the world.

I am searching for a copy of the documentation and schematics of this power supply. I see there is one original one on ebay

But  at 30$ + 50$ shipping to France = 80$,  I find the price tag much too large for a few pages.

I am sure it is not a very frequent item, but some of you may have it.

Schematics alone would be great !

Thanks for any help.
