111 Canon Inf 65mm - few Italian captured guns
http://www.amonio.es/canon_6517_ita.htm, couldn't have been used from 1930. Should be rather rare, along with unit 112 AT gun.
It's a detail, but a range is quoted as no more than 6500-6800 m (now 142)
https://it.wikipedia.org/wiki/65/17_Mod._1908/1913 - 6400m
http://www.regioesercito.it/armi/65-17.htm - 6500 m
https://en.wikipedia.org/wiki/Cannon.../17_modello_13 - 6800 m
(the same for Spanish, Italian and RSI weapon #31 and Romanian #249)
Spain OOB33 units 420, 421, 474, 475 - icon is wrong long-barrel twin-trail field gun for the first two, and bigger 2120 for the latter - they should be unified (Republican OOB uses 2109, which seems better considering small calibre; Romanian OOB uses yet better 2108)
Same for Italian units 320, 321.
RSI units 320, 321 should be unified as well (they use bigger single-trail field gun 2110)
Instead of generic photo of some different infantry gun for Spanish guns, 2646 or 2647 could be used with clear 65/17 gun, or Italian 16169, or there is a nice WW1 photo

113,114 Canon Inf 70mm - standard Spanish inf-gun from 1930.
Range was 5000 m

(icon might be too big, used for FH - might be 2109)
It could be added also to Spain OOB33 - Nationalists had even more of them.
115 Canon Inf 76mm (Schneider) - probably Soviet
https://en.wikipedia.org/wiki/76_mm_mountain_gun_M1909
Picture is wrong long-barrel FH, Romanian OOB uses picture 23043
(icon might be too big, used for FH - might be 2120)
116 Canon Inf 105mm - too small icon -
http://www.amonio.es/obus_montana_105_11.htm - best seems 2115 or 2122
Range is 8000 m according to that page and 7850 m here
https://en.wikipedia.org/wiki/Canon_...1919_Schneider (now 120)
Greek OOB uses photo 1221 for this gun.
Same for Spain OOb33 units 59 (already mentioned) and 477, using wrong long-barrel icons.
Spain OOB33:
Apart from mentioned above:
476,479 Canon Inf 75mm (leIG-18) - too heavy howitzer icon. German OOB uses icon 2120 and a picture 9404
478,480 Canon Inf 150mm (sIG-33) - German OOB uses icon 2116
482 25mm Canon AT - not used, especially by nationalists (French gun)
483 37mm TaK 30 - it was ordinary Pak 35/36 from the beginning
http://www.amonio.es/canon_cc37_pak3536.htm
A dedicated icon for this and 461, 484, 487 is 8007
485 45mm PTP Obr.32 - a dedicated icon is 8022
486 47L32 Canon AT - a dedicated icon is 8029.
Photo is 65/17 infantry gun, not 47mm Breda AT. Could be 16151, like unit 462 (although in fact this is newer Modelo 1939 gun, what is evident by spoked wheels).
Same icon for unit 462 CTV C/C 47L32
488 50mm PaK38 Azul - a dedicated icon is 8010
