Within the 686 and 641 Topics, various discussions have taken place concerning the unusual extensions that can be found in many box inner end-flaps, or the inclusion of additional printing on an inner end-flap. These extensions and additional printing seems to indicate an experiment by Meccano that would enable a retailer to write the price on the box, leaving that inner flap exposed while on display which can then be hidden once all the flaps are closed and the box and model are sold.
As these have been seen in both British and French boxes, I thought having a Topic in both British Dinky Toys and French Dinky Toys would be impractical so I hope I am correct by commencing this Topic with the Dinky Toys Technical Discussions!
The following images are three examples of these unusual inner end-flaps, in a possible order when these occurred, the 1st version in a first issue box, the 2nd in a later issue lighter yellow box and the 3rd being an example found on a French Dinky Toys, the 510 Peugeot 204.
There are undoubtedly many more so hopefully, other collectors can add to this Topic..
