hi willian, i know what you mean mate
there's a flaw in the movie;when kelly together with oddball come to the camp where the 3 shermans are, they go to one where morriarty is working on the engine,on that one as oddball explains (loud music,speaker bla,bla,bla)you see the speaker on the right side (i guess it's for filming purposes only) in the rest of the movie you will not see that one again
only were oddball in on top and there it's on the left
also if you make a shermie from the movie you can make one with exended fenders or not (even on oddball's sherman in one scene you see it with and the other take without ext.fenders) as there are so many more mistakes(hey it's a funny movie
)
