AARG, I picked up an old Mono 1/48 P-61 at a local thrift shop. Looked like it was all there, even the Shep Paine diorama sheet. But alas, one of the nose gear doors isn't on the sprue or floating around in the bottom of the box. Revell is no longer in the spares business. So I guess I get to do a diorama of a plane getting it's nose gear doors fixed
It shouldn't be terribly difficult to smash-mould a replacement. Use the other door to help you make a pattern from balsa, then heat up a piece of sheet plastic over a candle and pull it down over the pattern. Use 2 sheets of different thickness to build up detail to match the door you have.
