Ah Jim Lad!! - No not those kind of pirates! Plastic figures have been copied by unscrupulous manufacturers for as long as there have been plastic figures. Not sure what damage this does to profits or brand reputations but it can provide cheap figures and sometimes unusual options for the gamer.
From the same source - Afrika Korps - these saw a lot of service on my bedroom floor! The officer was painted as a naval captain for some reason.
Where I got these I don't recall - possibly a Xmas cracker - they are better quality than the first lot (despite the blobs on their helmets) in a slightly harder plastic which shows the detail more and they are slightly bigger.
Now! What have we here? These are 1/72 copies of the Airfix 1/32 Soviet infantry. Once again this provides a hint that pirates use sophisticated pantagraph technology to resize masters when they copy them - I have seen this done in either direction - I used to have a set of 1/35 French made from the OO/HO Airfix set but they were horrible and I got rid of them. A company called supreme also made copies of Italeri Napoleonic figures in 1/32 which were never released in that scale and those cheap 'knights' you can by in toyshops and supermarkets are pirated from Italeri's Crusaders (also probably the1/72 set). I am personally quite pleased with these as I always considered the Airfix 1/72 Russians to be a poor set and wished they had done this to them!
They did a whole selection - mostly Esci - which I have integrated into existing units made of their plastic brethren but as you can see from this dispatch rider Airfix got in there too! These were all WW2 and modern figures but I did once see (in the old military museum in Prague's Schwarzenberg Palace) white metal Esci Napoleonics so there maybe more out there!
