First of all I have to apologize but as a Frenchie I can't speak Czech language so I try with my scholar English...and I hope this post will be understandable for everybody.
I'm a modeller and I'm just at the end of a modelling project about a Sherman "Firefly" IC from the CIABG and after reading the Capricorn book about the CIABG I need some infos which perhaps you can provide me :
*When and where exactly the CIABG exchanges their Sherman "Fireflies" for the Challengers ?
*How the tracked CIABG vehicles went back to Czechoslovakia : by road or by rail ? If by rail, when and where exactly the vehicles were put on the trains ?
