Takom, noted for their military vehicle kits and also 1/72 kits of Bismarck's and Yamato's turrets amongst others, are bringing out a kit at 1/35 scale of a Sea Dart launcher with missiles and a Sea Wolf launcher with missiles and you get both in the same box. In the USA it will retail about $40 so I would imagine about £40 in rip off Britain.

(I have no connection with Andy's channel I just enjoy the builds he posts, I've learnt a lot from him over the years)
