The 88mm gun was equally fiddly - but what a welcome thing it is.
The halftrack has always been great conversion fodder. Here is one of the easiest - 20mm flak gun by Fujimi, trailer from the Airfix US halftrack kit.
JR's splendid (and forgivably overscale) Sdkfz250, complete with contemporary German infantry.
The second release in 1967 was the WW1 'Tank Mk1'. No doubt it would be possible to find fault with this models but it should be remembered that for a long time this was the only Great War vehicle available in this scale at any price!
1968's single release coming soon!
