I am planning on building the 1/35 IBG Skoda 100mm vz 14. I'm thinking of making it a Spanish Civil War piece. I know the Republicans got theirs from the USSR. Nationalists got theirs from Italy .. Obice da 100/17 M14. First, what colors would they have been from their respective sources? And is there any big differences with the Italian version? (I'm thinking they were war booty from WW1 and left at "as from the facctory".
