Yes he is. German infantry officer from the old Foundry TYW range :
The twins sculpted him as a Gustavus Adolphus lookalike and lord knows how many times that head was used for conversion jobs before manufacturers started producing GA personality figures.
I painted the drummer and the sergeant in that Foundry pack pic, about 11 or 12 years ago, and a dozen or so others from assorted packs in the TYW range, very nice figures to paint, still among the best out there for the period.
