Thanks everyone,
I'm thinking of building a SM.79 to accompany it. While researching it looked like many SM.81 were replaced with SM.79 during the war.
That Camou pattern was fun to do, I had to keep reminding myself to make random patterns, otherwise they started to look the same.
I think I might try one of the brown/tan/green/red coloured painted schemes next time - just for the challenge.
