Hi Gregers,
I bought the kit when it was brand new back in the early seventies. As I remember it, the kit had major fit problems in the wing/fuselage join; a spartan cockpit (remember, this was in the day when if you wanted detail, you pretty much did it yourself); along with the aforementioned exhaust shape. With work it can be a way cool model. SAMI did a Richard Corruna section three or four issues ago, definitely a reference starting point. Almost forgot...the decals in the kit were very poor, I ended up buying some from a company long gone. Wish someone would do this aircraft...I think it is very unique!!!
