One of those days where you take one step forward then two steps backwards.
While attempting to make an easy modification to change an F-4M to an F-4L I broke part of the underside of the kit. Hearing a piece of plastic, which is not simple flat surfaces, ping off into the depths of the stash and possibly into the mouth of the carpet monster is not exactly the way to start the evening

The good news is that while starting the search for the wayward son of a gun piece of plastic I found a Maintrack P1101 conversion set which I was thinking of using to provide the basis for the cockpit area of the P1121 "B" variant designed to GOR339 which was the General Operational Requirement that lead to the TSR2.
