Itinerant Air-Cooled

I am missing the cooling flaps that sit at the bottom of the upright fan housing. These would be connected to the t-stat and divert the flow of cooling air during warm up.

Also, I need the piece of cooling tin that sits below the 1 & 2 cylinder/head cooling tin. This piece attaches to the rear (Muir's rear) of the head tin.

Thanks, any help would be GREAT!!!
