Mrs H and I were walking around Chester's Rows yesterday. Quite by accident and without any contrivance, we came across the Chester Model Centre.    Being allowed in, I went to the aircraft kits in the corner of the ground level. I came out with this....     Big box, big problem. I can't exactly hide it can I? Herself was guarding the front door.   "How much?"   .....er £25......"   "That's not bad value", she says.   Jaw pic
