H is for Hollow-cast Highland Heroes

A couple of mysterious figures here, both painted in the same way, same colours, as Gordon Highlanders, both made of the same shade of the same very tinny or brittle, red polystyrene, both semi-flat (demi-ronde), both have very thin, oblong bases, but both completely different sizes. And both probably from hand-held, hollow-cast moulds, converted to injection-tools.

However; for all their similarities (identicallities!) there are some very striking differences, in addition to the size, are the facts that the second (smaller) figure, is almost childlike, with a'toy' gun and he has a huge red plum water-falling off his Busby, absent from the first (who's headdress is more like a Guard's Bearskin), he has more - the look of a Doll's House accessory? While the first figure - as well as having a 'bearskin' on his bonce - is lacking a sporan?

Using Joplin's The Great Book of Hollow-cast Figures (which also contains solids and composition) as a guide; Nobel make a 40mm one who's close to the figure on the left, but his legs are more at ease to this chap's at attention, there's nothing else close.

The one on the right ('Baldrick'!) is similar to a pose by Fry in hollow-cast, but it's more of a passing resemblance than the same tool, and while there are a couple of others in the Unidentified section, nothing really looks like this chap?

Can anyone add anything; they came separately, years apart.
