I need to find or make a "like-original" radiator cowl for a 1957 MkI 2.4 liter that I am restoring. Part C11775. Does anyone have any ideas where I can find one to buy or copy??

 

I believe the original ones were Bakelite, and I haven't ever seen one in the flesh. I too would like to find one for my 3.4, but I'm not sure that there are any floating around.

 

I have one for the Daimler,
but I bet they are not the same,

 

So Barratt's reckon part # C24965 will fit, same as later Mk 2 models.

I acquired a free-be which looks similar to the Barratt product, from a friend who gave up trying to get it to fit. Fortunately, I had my radiator out at the time, but it still took a lot of jiggling to make it adapt. An then there was the joy of re-fitting it when the radiator was re-installed.
A lot of wailing, gnashing of teeth and airborne tools was the result...........
