looney, as i had posted to you earlier, some modeler go to extreme lengths to have precisely detailed models. there is a thread here where several people debated on the precise look and placement of the rudder pedals on a German plane. all of which gets buried as soon as you put the fuselage together and the canopy on. i just spent a month building the interior of a 1/48 B-29, interior seats, tables, gage faces, bunks, bomb racks, rear gunner compartment, etc. soon as i but the fuselage together, all gone, never to be seen again.
as to the little broken piece a tooth pick and a bit of putty, and super glue. if you cab see it you can reach it
