The hollow cast figures look like W.Britains - should be easy enough to trace them, but probably not much value in a played with condition.
Some of the flatter pieces look like home-cast figures (possibly 1950s) made using moulds similar to the ones Prince August sell. Although the moulds back then were gunmetal not rubber.
The home-casts could include ships, subs, and aircraft (I've seen moulds for them).
Probably not a huge value more of an interest item.
You see them occasionally in local auction houses and they don't fetch a lot.
