I saw this in a local shop last week, it was £25 which works out at
very good value as the individual kits are at least £4 each nowadays.
Plus there are a number of kits in the box - DUKW, GMC truck, LCM, LVCP
and maybe others - that Airfix haven't sold individually for ages.
The coastal emplacement model was originally intended more as a toy I think, but with
a bit of work it could make a good diorama setting.
The one odd thing is that the single aircraft in the set is a Bf109 - considering the
virtually non-existent Luftwaffe presence on D-Day, a Typhoon or P-51 would be more appropriate!
