Hello Toby
It is a terrible shame but I cannot see the pictures you posted because my computer will not let me. I love the US decal option you get with the Smer kit, I did build what I thought was a good looking effort from this kit until some idiot knocked it off the shelf and accidently trod on it. If I remember rightly I made the engine bits that poke out the sides smaller, thinned down the struts as mentioned earlier removed those awful cast in roundels. Being lazy I stuck a pilot in so I would not need to detail the interior.
Best of luck
Alan.
