Yes, I have an original manual covering specification, operation and circuits.
Yours FoC, the deal is though that you scan the manual and upload it to BAMA, KO44B and similar archive sites.
If you agree to this then PM me your name and address.
Presumably somewhere I have an 819 probe, wonder where?
