The OP has the underhood pictures in his link to the other post in the Artnz/Butler forum.
To me at least, the radiator support (I guess that is what that is anyway) and at least the front picture with the "wings" next to the
oil cooler opening would be a dead givaway to someone who knows the manufacture. At least that is my opinion, which means D--K.
Edit:
Man, that is a long way from the radiator to the engine. Unless that is just the way the photo was taken, but I don't think so.
