Blaupunkt Frankfurt - looking to identify

[mac73s]

I would appreciate some information on this radio - what year is it, and were all Frankfurt radios 'stereo', or could they have been mono as well. Thank you.

The model 7639670 is a mono Frankfurt. The A prefix to the serial number is '69-70, I believe. (Others will know more on that.) I have a B prefix 7639670 in my early '72.

Arne - thank you for the prompt and helpful reply. I was going to make an offer on the radio, but not now in learning it is a mono unit. And yes, the 69-70 timeframe would be consistent with the car it is presently in.

Correct, it's a 1969/70 Blaupunkt Frankfurt US mono radio

I have a B prefix 7639670 in my early '72.

To be correct you need a prefix "C" Blaupunkt Frankfurt for your early '72

Can you please tell me what a prefix "G" Blaupunkt Frankfurt stereo is correct for? Thank you.

Can you please tell me what a prefix "G" Blaupunkt Frankfurt stereo is correct for? Thank you.

Here is a side photo of the "G" prefix...being offered to me as correct for a 72 but want the experts opinion..Thank you.

Yes, that would be true, if I were at all concerned with "date correct-ness". But I'm not. Don't tell anyone, but my Fuchs are a few months to late for my car also! Oh, the humanity!

I don't think any stereo Frankfurt is correct for a '72. As far as I am aware, the factory only installed mono. (Dealer installed was different story.)

The prefix letters were one per year.

A = 69-70
B = 70-71
C = 71-72
D = 72-73
E = 73-74
F = 74-75
G = 75-76

I'm pretty sure I had a G prefix in my 914...

Prefix "G" correct for 1975/76
