The caption states it is "real restored" but actually this very convincing Marder III is the result of a conversion project.
An Englishman has done what I once imagined could be done, back in the 1980s. It is Mr. Alan Swatman who has converted a Swedish/Czech tank m/41 into a German Marder III tank destroyer.
I learnt this from the latest issue (December 2011) of that most excellent British military vehicle journal, Classic Military Vehicle.
On the one hand it is obviously a successful conversion, using also a genuine Pak 40 AT gun. On the other hand there are very, very few Swedish m/41s around. Well, perhaps the information on the web I have found is not quite correct in stating an m/41? I suspect that what Mr. Swatman converted was in fact a pbv 301, i.e. an armoured personnel carrier based on the m/41 tank. Perhaps someone reading this can confirm my suspicion?
