This is all I know about these figurines;
Edgar Rice Boroughs E'zine...scroll down about half-way.
The figures illustrated above, will be originals. probably from Germany (?), and are about 8 inches high, hollow, slip-cast bisque (or;Parian Porcelain) mouldings in the style of Fairings, which they may well have been issued as over here...there..Europe. Doh!

Thanks for that Paul (both Pauls!)., and it's a different Foulds altogether, in fact it's Gem Clay...when it's not Heinz!
"In 1932 the Gem Clay Forming Co. produced a series of Tarzan plaster statues which were offered by various sponsors ........ The insert sheets/sets varied for the different sponsors. One side features images of the 10 numbered statues along w/color chart and offer blank. Opposite side advertises Foulds/Heinz products. The main difference is the statues offered. Most are same from set to set, with a few exceptions. Foulds offers "Three Monkeys" and "Witch Doctor" statues while Heinz offers "Kerchak The Ape" and "French Sailor" statues and sheets have different layouts".
