This action happens close to the village of Quatro Casas - as you can conclude from the above picture - and it portrays the two dreaded Moorish Tabors (half battalions of 2 companies of infantry and one of cavalry each) of Melilla, east Morocco.
The Moors were coming from North Africa and belonged to Franco's African Army who became famous for the first history's airlift (with Hitler and Mussolini's help), its fighting prowesses and also its cruelty.
All non-metal figures are these kind of conversions. The basis is mostly Revell WWI German bodies with heads from the Esci Muzlim set.
Loctite Special Plastics gives a good bond to soft plastic parts and was used in all figures needing a new head.
