Workman Transitest

[ewd]

First off, I apologize if this is in the wrong forum category, but this appears to be the closest I can find for an appropriate category. I was recently given an old "Workman BZ8 Transitest" transistor and diode tester. Old, but seemingly in very good condition. Does anyone have any information on this tester, such as a copy of the original operating instructions? I would love to be able to to use it, but I want to make sure I can use it correctly. Tried to Google it on the Internet, but apparently it's too old to be Google-able. While I have new DMM's and other test equipment, I think it's great to be able to put these old units to good use.

The instructions should be on the back of it, no?
Here are pics of the front & rear.

Thanks! Mine doesn't have the label on the back anymore.

Hopefully it is readable enough.
