Bearing in mind the original post and its information, would the Giulia GTA SA be an option?
It is listed with a top speed in excess of 240km/h and was built 1967-68.
Haven't been able to find any interior pictures though.

I think Olaf might be right when saying tipo 33 although the few cockpit pictures in the Collins/McDonough book does not look similar.
Hi Richard & members,

On the OKP site, rev counter and odometer for TZ and GTA are 125mm in diameter.

Ciao, Olaf

The calibration of the instruments is the same as TZ, just compare the photos.

However, there are significant differences;

Firstly the orientation of the numerals is completely different, TZ - Cannot vouch for TZ2 - are as all standard Alfa gauges. Rotation starts at about 7 o'çlock to 5, as posted by ARGTAReg, above. However, I do accept that the rev gauge in question is more appropriate for racing, since the rev indicator will be in the 'sweet' vertical position more often when racing.... but in my car the vertical position needs to be at 6 o'clock otherwise it is obscured by the wheel.

Secondly, no TZ has auxiliary information within the instrument ie, RISCALD. or GENERAT.

Thirdly, it is odd that the two instruments each have a GENERAT. indicator, surely only one needed?

Finally, Domo75's gauges at 125mm seem small compared to TZ instruments posted above....but nothing to hand to measure!

Just my take on it all....

Richard

Edit; I think all TZ production finished by 1967, but instruments in question are dated 14 Giu 1968!
SA dashboard was the one from GTA, with manometer in place of tachograph, but Richards’ observations about gauges in question are correct. Well, I have to admit that those two gauges were not ‘standard’ TZ instruments. I have controlled period ones, and they are different at rear. Those two remained mysterious pieces. However, all authentic TZ (big) instruments were (are)120 mm diameter.

Hi Domo75

We seem to have ruled out everything except GTAm instruments!

Ruedi posted a really useful link in post #15 which should be examined in detail.

A cursory glance suggests your speedo is very similar to those posted as GTAm, except there does seem to be some lettering to the LHS of the needle pivot....could it just be light reflecting on the screw?

The rev counter differs....red needle or is the a trace 'max' rev needle also that mystery GENERAT. indicator...

Hello Domo75,

It is really beautiful parts !!!!

By the way, the 14 GIU 1968 is not for GIULIA but for GIUGNO which is the month of JUNE in Italian ... so part was built/sold on June, 14 1968 ...

Cheers,
Patrick

These instruments are puzzling.

I agree about the stamp meaning June, 1968. There is also another stamp shown on the housing: 4.78.

I wonder if the 4.78 indicates that the instrument was made for a 9/43 differential ratio? If so, why would an RPM instrument (based on the lighting arrangements, I presume it was the tach, not the speedo) be stamped that way? And how would a 9/43 differential make sense on a 260 km/h car?

BTW, this is one of the many moments where I miss Papajam a great deal. His knowledge of obscure facts, documents and parts had immeasurable value. Maybe he would have known something about these instruments, maybe not. What little I know of him is that he probably would have liked this puzzle, too.

To follow on from the previous post there is another little puzzle for historians....

You will note that in post #10, 5 of the 6 gauges states "Made in France"and brand "Jaeger" whereas our mystery instruments clearly state "Jaeger Italia" and "Made in Italy"

I wonder when production started in Italy?

Licensed for production originally a Swiss company bought by Smiths, so who knows who they granted licenses to.... maybe someone pointed it out ...it has a temperature warning light,

The older I get.. the faster I was....

Momo manufactured a series of contemporary drivers signature wheels, I assume during the '70's. Ickx, Andretti, Lauda, Hunt et al.
The Ickx wheel looks exactly the one above, if you ignore the signature... Several for sale on eBay. May have been the "MOMO Prototipo" Series...

The original ones were 34,5 cm Momo, for 7 holes hub, now almost impossible to find. Anyhow actual 35 cm Momo (6 holes) is similar in shape, and easy to trace
