I did have a bit of a brainwave part way through one episode, recalling I had the Too Fat Lardies Through the Mud & Blood inter-war PDF supplement Triumphant Standards. Unfortunately this doesn't include any Spanish Civil War material but does have some very useful stuff on the German Civil War which will be useful when I find that bag of Scheltrum miniatures I bought a few Salute back!
However, the Lardies are a good bunch and they have released online articles and army lists covering the Spanish Civil War for Chain of Command which is full of really useful histories and unit TO&E's.
The downloadable lists available are:
Milicias obreras (Workers Militias)
Milicias del 5º Regimiento
Asaltos, Carabineros and Guardia Civil (Security Services)Requetés
Tercio de la Legión (Spanish Foreign Legion)Peninsular Army Infantry
Ejército Popular de la República (Popular Army)
Corpo Truppe Volontarie
Raggruppamento Repartí Specializzati
Great stuff, I can feel the ooh shiny butterfly might spread his wings soon!
