Smiths Instrument Tester SR/D409 - looking for Instruction book

I bought myself a little toy and would like to make sure I use it correctly…
Would anyone have a copy of the instruction manual for the Smiths Instrument Tester and could share it?

Tadek,

If it’s the one in the little wooden box that tests moving iron and thermal gauges and senders, I have one at home and I do have the instruction book. If no one else offers I’ll send you a copy at the end of the month when I get back to the UK.
