After much trimming and sanding the new canopy more or less fitted and was glued into place. So far so good, except that when I picked the MiG up to begin painting the canopy promptly (and perhaps predictably) fell off. Fast forward a few days and the canopy - with the aid of more glue and filler - appeared secure.
A coat of Revell silver was brushed on and the troublesome canopy painted over. Basic East German markings were robbed from another kit and the ensemble topped off with a coat of gloss varnish. Up close it looks every bit as nasty as the preceding description would lead you to believe.
In the photos it looks rather better!
