Here is a list of some Captains & Calvary sets that were on eBay a few years ago:
Japanese Marines, 1942 (could be the set you have a photo of earlier)
Japanese Navy, 1941
Slovakian Infantry, 1940 (I have ordered this set on my new Hiriart order, but 1941)
French Infantry, 1940 (I wonder if these are not the same as the Fortress Troops above)
German Womans Luftwaffe
German Infantry, 1940
Polish Infantry, 1940 (I ordered & received this set from Hiriart last year, but 1939)
Polish Mountain Infantry, 1941 ( I really would like to see this set)
Russian Infantry, 1941 (I believe the earlier photo shows 2 figures from this set)
Russian Navy, 1943 (I would also like to see this set)
German Navy
Does anyone have any others?
