One of the two turned up trumps!
This is The Butler-Dragooner, no.131 by Richard Forster. Made in 1943 as one of a series of 18th century Prussian Fussoldaten soldiers, they were given to Hitler on his birthday in April 1944, and there is a well-known photo of him with Himmler, Fegelein and Schaub looking at these figurines.
I'm delighted to be able to add this to the collection!
