According to a quoted Russian book, BA-10 carried 49 rounds.
I've found a proper green icon 50 for unit 110 Landsverk 182 (I don't know if there is winter version)
-----
Artillery:
42 50mm M38 AT-Gun - better icon is bigger 56
48 40mm AA-Gun - picture is generic SP-1 gun - may be 6080 instead.
Nice icon, probably conceived for Bofors 40 mm, is 2801/2803
78 76mm K 02 FG - better icon, and different from unit 77, is 2111 (used for its Polish equivalent)
80, 81 122mm H 09 FH - better icon is 2115 (it had much shorter barrel)
82 122mm H 38 FH - icon should be twin-tail, eg. 2105
The majority captured as early, as summer 41, so probably their use should start earlier, than 6/42 (

83 114mm H/18 Bty,
87 122mm H 09 Bty,
134 122mm H 09 Bty- as indicated in Finnish Weapons thread, they should not be Off-Map Arty.
It seems from Jaeger Platoon, that the only Off-Map Arty (heavy) available for Finland before 1940, should be French 152mm H/17 (same specs, as 155mm mle17, with range 11km).
It should be added as new weapon, and replace eg. unit 87, available from 1/30 (

88 122mm H 09 Bty - name should be H 38, photo: 23180
The majority captured as early, as summer 41, so probably their use should start earlier, than 6/42
90 152mm H 09 Bty
144 152mm H 09 Bty- their weapon had range 9.5km, so it should be 200 to retain these units as off-map arty
