Is this the right stuff?

These are the documents laid out as primary data for members to make their own minds up about.

my conclusion from it is that all 74 USA market models had pile carpet as standard and there was no further option up (or down).

the carpet was hair yarn for the first part of production.
two color wool yarn for the second part of production.

jeff bowlsy has the change over date for the black carpet pretty closely pinned as a result of the LE register info.

who knows when the brown changed over.
from what i can tell from the L jet data i have its later in the production run.
all this only comes about because i have stoopidly (IMG:style_emoticons/default/calvin.gif) collected data on L jets to settle an esoteric question about vacuum hoses. (IMG:style_emoticons/default/headbang.gif) that data showed cars only had loop pile. as does my humble base spec 1.8 (with factory optioned sway bars (IMG:style_emoticons/default/devil.gif)

same goes for beige.

beige interior even less common than brown.

anyway its up to restorers to make up their own minds.

i don't think there was any perlon or velour carpet in USA bound factory 914s in 74.
there was velour in 911s.
but thats an opinion and conclusion i draw personally.
and who knows, maybe someone asked for it and was on the inside enough to get it?

they definitely all used hair yarn (while it was on the books) which produced that white fuzzy fibre look.
for that info and break through i am eternally grateful to @scallyk9
