I am currently working on a Ta 152 C model and while researching found that the cowl flaps are peculiar in their shape. So off to google I went and I found pictures of the db-603 in the Daimler Museum in Stuttgart (of all places, that is about 30 minutes from where I live).
Now, the sources I have say that the engine in the museum is displayed with the cowl of a do-335, but on closer inspection of various photographies, the cowl in the museum does not look like a do-335 cowl, it looks much more like a ta 152 c cowl.
The first image I link to is of a do-335 cowl.

These two pictures are of the engine in Stuttgart, quite different, for example there seems to be an iregularity on top. Maybe the gunthroughs of the 152, the do-335 did not have those.
The cowl flaps are different too, much wider and with the upwards angle wich coresponds with drawings of the 152.

So, does anyone know more about this? Is this actually a Ta 152 C cowl?
