Kotza refribase

Does anyone have the kotza refribase and/or the refrepair manuals to sell as I am currently studying as a refrigeration apprentice and been recommended these

Hi,
It will be hard to find a kodza because it's close ,,finish.
But if you search on the net , you will probably find one occasion .
It's a very good book , i have the last french version , it's a very great book .

My mate had kotza, used to leave it on his van seat so the supervisor thought he was up on things... Nice move!
