WTB: "Knobs"

[maverick]

For a 67 Blaupunkt radio.
Someone must have a set laying around
Thanks

[Cornpanzer]

I have the black rubber ones…not sure if that is what you need.

I have these: D0003A51-05A2-4034-8061-F9ED80267A33.jpg

Thanks Camarilla.
Knobs would have a flat front

[camarilla]

Unfortunately, the flat ones are in my car. These were spares that came with my radio trim set and are the only ones I have to spare!

[Cdegenaar]

These what you’re looking for?

When did they change to that flat plain rubber from this style as pictured in this Blaupunkt brochure which features the fitting kit for Porsche with silver dash? Isn’t this a 67 dash?

I have some of the fluted silver secondary knobs shown behind the main black knob in radio makers own brochure. Got quite a few flat rubber Blaupunkt ones among about 100 assorted Blaupunkt Becker etc original vintage radio knobs. I’m in U.K.


With caveat that Porsche own printed materials sometimes use earlier photos this is a photo of a radio in an accessory brochure with this print date on the back

The silver fluted auxiliary are quite hard to find I have some that appear to be same or similar to both variation pictured per Porsche accessories catalogue and Blaupunkt catalogue with Porsche example. Have quite a variety of knobs and face plates and fitting hardware not just Porsche but Merc, BMW and other marques. Quite a few plain black rubber knobs

Also lots of Blaupunkt period material for reference some I might sell. A list of what was required to do it things right can be gleaned from those. It is a typical configuration management thing.

A radio box of certain model of radio ( some with the secondary box) was the same at core regardless of car marque or model. For particular radio model within Blaupunkt year range it was the Blaupunkt range of boxed installation kits that tailored these plain base radio unit box(es) to the dash architecture of the marque model and year. Kits typically came with with faceplate, knobs, wires, brackets, nuts bits screws and sometimes speakers with grille to suit.speaker. Each of the installation sets had a Blaupunkt unique reference number and a bill of material tailored each with parts. These kits changed as the dash design evolved as did the model of radio. There is more than just matching the radio model name and prefix letter get the right configuration if seeking reasonable authenticity.

With car design lead time sometomes the model of radio for Porsche is a tad behind the prevailing car model year. Obvious reason why. Then some other radios models might get introduced part way through car model year.

Example comes to mind being the Blaupunkt Bamberg CR appears on the M-options only early calendar 73 for the Porsche that was launched during calendar 72 — appeared Feb so about half way through the 73 model year ( that’s if memory serves me). No doubt such things happened often as radio models from Blaupunkt Becker etc got released and approved for option list or retired from the options list when radio type no longer made. The Becker top of range CR model for 73 model year 911 was actually a quite specific Becker model number that when look into is fair bit earlier than what might be asssumed — fair bit earlier Thant be incurred Ines often retrofitted. I’m less familiar with 67 car and radio configuration nuances.

With dealer and aftermarket installs after car arrived (not factory fitted per sales papers or kardex) there is more of a free for all. Also regarding todays fashion of retrofitting to get rid of later radio additions. Although better than a 80s or 90d dogs dinner in the dash that perhaps with a tad more thought and care could integrate the retro one much better for probably same budget paid to source period replacement that was put in. Devil is in detail.Not a priority for some but it can jarr in an otherwise nice interior and dash.

Nobody makes or sells those knobs. Nobody. You could use two hood pull knobs drilled for the shafts and drilled and tapped for set screws, the shape is the same. Looks like one in the second from bottom bin on the left. Blaupunkt models changed mid year and the 67-68 models used new rubber primary and plastic secondary pointer knobs. Do late 67 models use the rubber type or did Porsche keep the 66-67 type for 67 model production?

Interesting. I pulled out the rubber knobs from my stash to photograph because that’s what OP had asked about buying by PM. I briefly had the one you note (second from bottom bin on the left) in hand today but didn’t give it much attention.

Seem to recall it is one of a pair. But have only one pair like that. Not sure if it is a Blaupunkt 911 one tbh but shape is similar to ones in my photos in dash (post #7) which is possibly why that pair caught my eye as I rummaged through the box for the silver fluted secondary knobs. Certainly a hard plastic, face is concave but didn’t flip it to check the mounting holes.

Incidentally the diameter of shafts of Blaupunkt radios did change about this time. In fact noticed shaft diameter can be different left vs right. Possibly if the secondary control has function or not? Not an issue if knob held by grub screw I suppose ?

I have numerous radios that I’ve accumulated over the years; below is a V….. (thinner) vs Y….. (fatter) shaft. I snapped these when units were to hand today but never really looked in that evolution in much detail because my interest is 72/3 era when the method of fitting knobs to shaft is different to these earlier ones:

I was looking for several years for correct knobs to fit my 1968 Porsche.
Found a useable option at "Chrome London" contact MikeSeer@gmail.com
They provided an early allen screw type that works for me.
