Storage always was / is / will be a problem with model aircraft.
I recall seeing a rather neat solution at a model show or similar a few years ago.
The post on this thread about a collection of 1/48th EE Lightnings prompted my memory.
The chap in question had built a collection of Lightnings (in every mark and squadron colour) as half models and had attached them to a vertical board. Looked very professional.
Anyone else recall seeing this?
