I have some suggestions as for Republican Spain and Spain, limited to pictures this season.
Republican Spain
86, 124, 143 Obus 75mm L32 - picture is Italian mountain 75/18 gun. Italian OOB uses 36901 for a field gun, which seems correct (by the way, it probably shouldn't be modern 75/32 gun, but rather one of WWI 75/27 guns, but I won't go into this minefield now).
88, 126, 145 Obus 76.2mm - picture is 18pdr, should be Soviet M.1902, eg. 19786 or 19802
93, 130, 148 Obus 105mm - I'm attaching a picture of Vickers 105mm
(95, 131, 150 Obus 114mm - I guess it should rather be short on-map 4.5in FH, than 4.5in long-range gun, which was accepted by the British in 1940 - but it would concern picture, icon and weapon's range)
103 Canon AT 45mm - picture is 37mm Pak, correct is 49
(107 Canon Inf 37mm - more specific picture of TR mle 16 is 30291 or 28004)
(111 Canon Inf 65mm - I proposed a specific picture of 65mm gun in the Polish OOB)
119 AmetralladoraAA - better Maxim-looking AAMG picture is 27141
121 Canon AA 37mm - picture and icon is AT gun - possibly it should be German 3.7cm flak? (Soviet one was introduced in 1939 only) - then icon 64, picture 141
153 Bateria 152mm - picture is 8in, should be Soviet 23256 (if it is M.1910 howitzer).
154 Bateria 155mm - picture is Soviet 152mm ML-20, should be 30290
159 Bateria 150mm - picture should be 17039, as unit 152 Bateria 150mm
164, 178 Mrtrs Delaunay - icon and picture is 75mm howitzer. It looked like this:
http://www.amonio.es/mortero_delaunay.htm
Possibly it's pm19722
186 Amet. vz.37 - picture is Soviet SGM(?). Correct is eg. 22114. Same for unit 214.
189 Amet Browning - picture is Vickers, should be eg. 31000 - or maybe rather its Polish 7.92 clone 29695, which was exported to Spain (I don't know, if M1917 was). Same for unit 210.
314 Esc de F.Amet - picture is some belt-fed MG - correct DP LMG is 27093, as unit 319.
325 Camion GAZ ZiS - photo is Polish Ursus, should be 165 for ZiS-5 or 166 for GAZ.
(331 G. Asalto LMG - could have a picture of LMG 27077, as unit 317)
362 F.Amet Montana - picture of Hotchkiss LMG is 27077, now it is Benet-Mercier.
(393 Potez 25 - much better icon is 483 of R-Z - it was a large aircraft with rectangular wings.
(395 Circo Krone - as far as I could find, Circo Krone was a nickname of a bomber unit - and this plane is just Kolhooven FK.51)
406 Vildebeest MkIV - I'm attaching a photo of Spanish Vildebeest, which looked quite different.
408-410 Breguet Br XIX - a picture is not Bre XIX, but rather some transport. I'm attaching a proper one in government markings
430 Douglas DC-2 - icon is single-engine.
(441, 442 CB Tiznao - all improvised APC currently have one icon - maybe for example these two should be given 2845 (from Polish Kubuś improvised APC)? Grey would be OK, for "Tiznaos" meant "the grey ones")
(443 CB Durruti - maybe a better icon is 457 with a turret? This unit has HMG, and a turret on a picture)
(445 Sadurni de Noya - I'm attaching pictures better showing the vehicle. It is usually known as IGC Sadurni, btw)
446 El Piojo - I'm attaching a correct photo of a vehicle known as "Piojo Móvil" (Mobile pillbox?) - from
http://www.fotosmilitares.org/viewto...=1963&start=30
(Unfortunately, I haven't found other information, especially to verify its multi-MG armament)
454 CB Bilbao M 32 - photo is UNL-35 (maybe a better one, that already used by unit 453). I'm attaching a correct Bilbao.
(472, 475, 477 Trubria M - in all cases a correct name is "Trubia" -
https://es.wikipedia.org/wiki/F%C3%A...rmas_de_Trubia)
(473 Artilleria M 16 - it's worth to give this Schneider CA1 a new icon someday, but as for now a better one seems 1916 (only lacking a wedge bow), than a turreted current one)
479,480 T-26 M 33 - photo in fact shows distinct Nationalist markings - I'm attaching a proper one (or even the Soviet one would do).
