Has anyone ever seen a Ju52 with the middle engine replaced by something like the D601 or D605 engine? This version has a massive radiator type thing just below the D605 engine and still retains the two original engines mounted on the wings. Just trying to figure out what I have a picture of. I don't want to post the picture until I find out a few more details.

I can only think that you might be looking at the Ju 252 which was powered by three Jumo 211 engines, though that doesn't tally with your description of radial engines on the wings.

This is just a regular old Ju52 with the radials on the wings. The nose engine looks like it was taken off a BF 109 and even has the circular air intake on the left side behind the exhausts. Took the pic to the hobby shop this morning and no one there had ever seen it before either.
