It might be coincidence since a lot of them look alike but has anyone ever compared the Alfa 33 one with the one in the Murena? I stumbled upon a picture by accident and am now looking at several pictures from the ones on Politecnic, Simon and Matra Magic and random examples of Alfa 33 ones and to the eye they look completely identical. However price wise the Alfa one costs about a third of the ones from the Murena specialists... For example: https://www.alfashop.co.uk/products/5031001-sud and https://www.simon-auto-shop.de/06033Also, I read on Roy's alternatives list that the 10 psi filler cap is kind of unique to the Murena but when I google around I see plenty of other 10 PSI rated caps that are short reach. They're all 60mm and around 25-27mm high though so maybe that's where the difference lies? <<EDIT:: I misquoted here because of this website: https://www.asap-supplies.com/products/driveforce-pressure-cap-short-reach-10-psi-206910 where 10PSI is followed by 80kPa which as Roy kindly pointed out is incorrect!!>> It would be really nice is the Alfa tank is a match though. Those seem to be relatively common.

Apologies Roy, I amended my post. I'm surprised but happy to hear that the tank similarity is common knowledge. I looked at your site http://www.matraclub.org.uk/Murena.html but didn't see it mentioned... I've done some further research into these caps and I get the feeling websites sometimes convert these pressures incorrectly. I found some people on forums mention 24mm deep 0.8 bar caps for other cars (e.g. early X19 apparently) but they also came to the conclusion they are very hard to find. Then I looked for pictures on the Matra specialists and found that the ones at Matra Magic are 4lbs according to the picture: https://www.matramagic.co.uk/2020/02/01/eu-no-change-here/Header-Tank-Cap-Murena-p381275839 I'm not quite sure what to make of that.

Ah that makes sense, Is the newer rectangular one also used in other cars like the triangular one?
It probably was but I never found out where it came from. (Does anyone else know where the larger rectangular header tank came from? Or what other car had it fitted?) Matra usually bought parts that were being made for other manufacturers and cars, as that was far cheaper than having to design, and make their own, for many common items fitted to all cars, such as door handles, electric motors (wipers & windows) interior mirror, column stalk switch assemblies etc. Even things like the radiator came from another car but with slight modification (brackets added) for the Murena. Those incorrect descriptions are really doing my head in. Especially when it comes to things that I simply don't know much about, it's extra annoying. And even on topics I am familiar with I still find it sometimes hard to determine if it is as advertised.
Never rely on photos for one thing as many use a 'stock' photo in their adverts. Unless it says that the photo is of the actual part, then treat it as possibly wrong. And many who advertise their parts as 'will also fit...' are very often wrong simply because they regularly do not know a specific car, like ours, and just assume it will fit. They are simply trying to make it seem like it fits lots of things to increase their sales. Roy
