912/356 alloy vin plate questions???

[mycarrera2.7rs]

I have come accross an early 912,
probably made in 1965 and on the alloy vin plate riveted next to the chassis stamped numbers it has TYP as 912
but the Heizerichtung Typ says 356 B T6 squiggle S 50,
I was wondering why a 912 would have what looks like a 356 stamped alloy vin pLate
can anyone throw some light on this?
many thanks

That's the Germany/Sweden market fresh-air heating system (so-called "European heater.") IIRC the 356BT-6 S 50 is the European market code for this type of heating system which was required in some markets.

Thank you for the info,
however I believe the information is incorrect.
The is no information about heaters or any other accessories in the vin.
The second number refers to the base Porsche model that the German TUV accepted as it's standard homologation.
Here a couple of vin number I have gleaned from the internet.




so it would seems that since this is an early 912, the base homologation was the 356.

Early 911 have a homologation TUV base of 911 as the car was mechanically different from the 356..
Anyway that is what I was told, any other info would be gratefully accepted.

I'll have to stick to my original answer but I'll hopefully fill-in some blanks here.
The German word heizeinrichtung means 'heating system.' The S 50 is the TUV acceptance number which is critical because some markets (mainly Germany and Sweden) required fresh-air heating systems (aka: Euro system.)
The ID plates you show in your photos are from 911 cars. These would carry a later acceptance code since the heating system was a later development and (this is important) is a totally different system requiring separate acceptance codes. A photo of your ID plate would be helpful.
As for the '356' on the plate, it refers to the "new heating system" which was changed by Porsche with the T6 version of the 356. Since this heating system was carried over to the 912, it didn't require separate acceptance, unlike the 911 system which did.
Acceptance code S 50 shows up in the 356B shop manual supplement as "Heating system type 356B/T6, acceptance code S 50; heater for Germany and Sweden."

All 83xxxx engine numbers for the 912 had the Euro heat exchangers. Which was only sold in Germany and Sweden. The 74xxxx engine numbers had the export heater boxes. Which was sold to the rest of the worlds market.

In April of 1965 was when the first 912 was built, for the market, to be sold in Europe only. It was first being sold in Germany only. Some were bought there and later exported to other countries. The official exporting of 912s was not until July 65.

Also the last build for the 65 356C/SC was in April of 1965. They were still being exported and sold in the US until July 65. As per Factory Service Bulletin dtd 27 April 1965.

What WFBowen and Jaems Thomsen say is correct
