Handwritten production number

[npvpositive]

I recently removed the windscreen in my 71S so have been able to see the "secret" handwritten production number for the first time.

Would this be a correct interpretation?

1 = production body
0 = coupe
1 - 1971
0053 = the 53rd coupe made in 1971 model year

Yes, that is the correct interpretation. Please PM the VIN and paint code to me.

Order number 53 of a 1971 coupe.

Is this an order number 43?

It is one of the multipart fahzeug-auftrag - production order sheets. These were raised on the production planning system from a confirmed order. This was era before integrated Systems so the S&OP, supply chain , assembly would’ve been done with paper, punched cards, telex etc — a much more fragmented way than ways of working in automotive operations today.

Not sure what the large four digit denotes. I have the fahzeug augtrag for my 73 RS and nothing like that is on mine. There are plenty of strike troughs and ticks and annotations in normal size pen marks as workers progressed the work tasks. Clearly checking if as in a to do list. Looks to have been marked by multiple hands consistent with car moving song an assembly line . This hasn’t got that year. The example in photo hasn't yet got the stickers either (normally affixed at right top) so presumably hasn’t yet had “marriage” of engine transmission chassis. Not yet brought together for the point it becomes matching numbers.

I think I might have posted the original of this image, can’t make out what is typed on the places where the three stickers get affixed. Possibly what’s typed corresponds to the numbers on the stickers that will be the match? However there don’t seem to be enough digits for motor transmission or chassis number format so perhaps it’s just the type of motor and type of transmission required eg 911/83 and 915/08 rather than a specific serial number?

M options are in the box at left (unless early RS in basic form) in which case little info there because Moptions would be blank as options were in the related conversion order for the first cars actually built lightergcweight and used as evidence for homologation.

RL is abbreviation for right hand drive configuration but that may not be the reason it is written here. I worked out this film that I screenshot this was during spring 1973 so 0043 possibly low about nine months into the model year 73 production ?
