Regarding the Towiphon. I ran a quick search on it and didn't find much, however I did find this book in German on Amazon
"Peter Thomas the unique German film composer, sometimes by his more experimental side. The people of bungalow records had the unique opportunity the Thomas own archive browse. For as much as nearly 3000 more or less short clips they searched 29 from the aie on the 2nd cd assembled. All instrumental office and with the emphasis on electronic sound generators. Peter Thomas is developed together with a technician a synthesizer (Towiphon) according to their own ideas, his abilities here massively apply. For those people more melodic pieces of this promise is rather less suitable. Who insight into early experiments with electronic searches, has a veritable treasure trove ahead. On CD1 is to hear what 17 young musicians today with this source material started. We are all very inspired and often danceable tracks.
Must! For people with open ears"
