I have a Matchbox Halftrack PK-78. Box front differs very slightly from existing image. Mine has the word 'Maquette' just below the signature. It also has the clear panel on the rear of the box and (c) 1974 Lesney Products. The existing entry for this kit gave a date of 1978, so I've changed it to 1974. I apologise if I'm wrong doing that. If I am wrong I will change it back to 1978. I'd be interested in your comments about whether the (c) copyright date is a reliable guide to the actual release date.
