OK, as per my WTB ad, my period correct Blaupunkt Frankfurt didn't quite work out (static only). Well, I bought it as one of two about 12 years ago off the classifieds on the long gone 914 Fan Page. I think I paid like $35 total. I actually got two radios--the other being an old Blaupunkt AM/FM cassette. I have the 914 originality book (can't remember the title right now) that lists fairly accurate radios for 914s. The Blaupunkts listed are "Frankfurts" and "Emdens", and I think "Wolfsburgs". I note some 916s had Becker "Mexicos". I do know that all 914 radios were dealer added, so the 914 could have had essentially whatever--I've seen the old Motorolas installed, and some no-name decks. Anyway, I'm planning on sticking with old Blaupunkts.
What of this old cassette deck though? It's got to be fairly old, because I saw a late 70's model online that was all plastic. This one has a metal face and cassette door (the door is what has "Blaupunkt" printed on it. I also note that this is a Euro-model--FM only does to 104, and the bands (three) are named "L, M, and U". Any ideas on model? No stickers on it like my Frankfurt has to help me. What about the little extra piece? That looks like where the speaker connectors hook up to. What do you guys think?
