NAP250 Bolt Down manual

Hey All.

I’ve got a bolt down CB NAP250 that I’m going to be restoring.

I was looking for a manual for it to print off and be with the unit, but I’ve come a cropper on finding one that early. Does anyone have a copy (or know if it even exists) of the original NAP250 manual?

This is the early model with the vertical PCBs.

Thanks.
