While not an expert on Winter War I found few things that struck me as odd in the list:
Winter War Finn Anti-tank Squad/shaped charges
-Can't recall these being in use, but SATCHEL charges were used in abundance.
Vickers Type E Light tank
-These hand't been purchased without TURRETS, but without armament and without driver's seat(!) Anything to save few pennies, eh?
Fokker D.XXI Monoplane fighter
Equal to the I-16 in terms of manoeuvrability
-hardly so, I-16 was a slippery one, BUT superior Finnish training and tactics often outset the disadvantages.
Bristol Bulldog Biplane fighter
-These were used only in the defence of city of Turku (located in southWESTERN Finland) against bombers. Slow Bulldogs had hard time catching even bombers. Wouldn't include this in the list as it wasn't used in the front.
Gloster Gamecock/Kukko ( remained in service until 1944.)
-IIRC these were used in training, if even that. CERTAINLY not in the front! "Remained in service" most probably means that these were finally scrapped in 1944 but doesn't mean that they were really used prior to that
So I would exclude them from the list.
Gloster Gladiator Mk II
-Has description of Gamecock. This plane was a frontline fighter.
Hurricane I fighter (They arrived just in time for the end of the Winter War. )
-Can't recall them being used in any missions as they arrived so very late. So I would exclude them from the list.
-One fighter that saw significant action during Winter War but was missing from the list was Morane Saulnier Ms 406
-Dunno how fighters work in the game but Finns didn't really use fighters to strafe enemy ground troops as it was deemed too risky for the few and irreplaceable fighters. However during the last weeks of the war when Russians began to attack over frozen Viipurinsalmi fighters were ordered to starfe nevermind the casualties.
