These are:
- Motional Feedback Speaker-Amplifier System mod. MF-800 (but then I found a much better PDF version on the web)
- Flash Unit PE-2410
- R-155 portable radio receiver (almost unreadable on the microfilm)
- R-510B portable radio receiver with cassette tape recorder
- R-531B (which is the one I was directly interested in, for a future restoration work).
Some National Panasonic service manuals from 70's
