Fallschirmjager Anti-Tank Rifle Finnish Lahti 39

So why a Finnish Anti-Tank Rifle?  Especially if I am using my project for Tunisia winter 42/43?  Well it's not so far fetched as you would think.  First off a Anti-tank rifle on ski's is to cool not to use.  Secondly the units I'm loosely basing my Fallschirmjagers on did extraordinary things in Belgium, France, and Crete before being transferred to.....you guessed it Russia....more specifically Leningrad...do you know how close Leningrad is to Finland?  Pretty close.  So as I stated not to far fetched for a Finnish Anti-Tank rifle to end up in the hands of Fallschirmjagers.
