They are definately scaled down Airfix bods, reproduced in Hong Kong etc.
They seem to be the same lot that make these play sets with 1/72 scale bods with oversized missile launchers and tanks,or khights with a tiny castle. Usually sold on Holiday campsites or tourist type places. Next time I see a bag of these I´ll remember to buy it or at least remember the name of who makes em.
See Link, Thanks to whoever tidied up the link

There were also some others that were around 30 + years ago like these, the horses were all in one pose and Hollow.
