    Default Chassis and engine number

    I think this makes mine a 1975 - a relatively late build?

    Engine number looks like 6/74?

    Is there anything else I can glean from this numbers?

    1975 is late build full stop!

    From what i can work out, that chassis plates relates to one of the last DS23 saloons built. A car with a carb - so not an efi. For that kind of car/ engine, the chassis plate should say 'DX4' (can't quite read it in your picture).

    Yep DX4. 5 speed carb. It looked like a late build but I wasn’t sure how late.

    Does it the engine number indicate 6/74?

    No - I don't think so. Well it doesn't work for my engine anyway - unless it was built in 1916

    1975 DS23 Carb cars begin with 01FE8501 - Reynolds give total production of all D variants for 1975 as only 847.
    I'd say your car must be one of the very last of it's variant.

    There does appear to be an anomaly with your plate showing 01FE963* (I can't read the last digit) adding 8501 and 847 gives 9348 so Citroen may not have used sequential numbering?

    That's calendar year production Chris - whereas the other tables in Reynolds (for serial numbers) are 'model' year'. The last D rolled off the line at the end of April 1975 - so a shorter production year and accounting for the very low '847' figure. Some of the 40K production in 1974 relates to 75 model year cars. In fact 4 months worth (1/3) but because production slowed, I will assume 9,200. Together with the 847, that would put 75 model year production at around 10K.

    We don't have first and last serial numbers for 1975, so can't do a crude calculation to estimate approximately when this car was built, but in previous years there seem to have been about 9600 Ds23 carbs in the first year introduced, then 6400 the next year. Given the total factory output fell to something like about 10K, if we assume numbers of DS23s similarly dwindled and guess maybe 2000 in the 10 months before production stopped? On that basis, this car (being the 1135th DS carb built) could be from circa Jan/ Feb 75? Only two months before the last car rolled off the line. All speculation of course!!

    Ok. Thanks for all your knowledge on the subject. I really appreciate.

    I wonder what the vibe was like in the factory. I guess they’d moved on the SM in their thinking although it was post 72 oil shock and sales of the SM wouldn’t have been great.

    I guess it would have been all about the new CX at that point. Lot's of transferable skills from the workers on the DS line, so no reason to be downbeat.
