Is this the right stuff?

Loop Pile cabin carpeting for USA markets...sounds right.

Of course perlon was used at the front and rear trunks.

The European market cars also had 'corduroy' seat upholstery, at least as an option (not sure if it was standard) but corduroy upholstery was not offered for USA cars.

you basically have all the documentation that establishes what went into USA market cars - and what went into ROW cars for just about every year on your website.

VW of North America or Porsche Audi produced the color sample books/boards for the USA market. you have these filed in your Factory Tech Publications section.

VW-Porsche gmbh Ludwigsburg produced the European (ROW) sample folders for the domestic home market and europe. these are filed in your Paint and Fabrics section.
Although what you appear to have Jeff is something more akin to pages from a parts catalogue with the sample swatches printed in. characterised by being printed in 4 languages. i have the fold out brochures for 74 and 73 which are slightly different format, published by VW-Porsche gmbh in germany and also in four languages. which match the documents you have in terms of range of materials.

its all there. inclusive too of the 911 range in the Porache Audi USA documents.
the differences limitations and the range.

bit time stressed today. but i will lay it all out in orderly fashion.

including additional material that makes it vividly clear. which are window sticker sheets for 73/74.

suffice to say. all and only pile carpet in 74 USA. black brown and cream.
initially at start of 74 using hair yarn. and then as the year went on transitioning to wool with the mottled appearance (or salt and pepper as you characterise it). though the brown also goes to the mottled appearance (seems to occur much later in year for brown probably because fewer brown interiors than black and it took longer to use up exisitng stocks of brown carpet sets at factory?). two color yarn threads is how i would put it for the yarn. at start of 74 its a repeat of 73 except perlon deleted in USA.

ROW in 74. perlon (needle loom) in hair yarn as base. pile in hair yarn as option. pile automatic option on all appearance group cars. whether 1.8 appearance or 2.0 appearance. basically a repeat of 73 but transitioning during year to two color yarn as hair yarn phased out.

-------

as a side note. hair yarn velour (or haargan velour) does not make its appearance in 911 range until 1974. before that 911 have perlon (needle loom) or pile. pile being the option. once velour appears, perlon is no longer used on interior of 911 and loop pile is the basic standard carpet.

hair yarn loom makes its gradual disappearance from the 914 and 911 range during 1974 to be replaced by pure two coloured yarns. my guess on that is the source dried up. carpet factory closure. discontinuted by manufacturer. went out of fashion and broad demand?
animal hair stocks too hard to procure? whatever. but hair loom has only recently come back into production and fashion in germany. i can guess why too. germany has a very advanced consumer attitutude towards sustainability and ecology these days. so hair yarn is back on the table - especially in the construction industry.
