I checked Transogram company in O'Brien book on figures and was surprised that the company started in New York in 1915 and filed bankruptcy in 1971.
During WWll they made figures out of sawdust and glue which were pressed into figures. After the war they made individual plastic figures with interchangeable parts. Horses for the figures had individual poses. They started making the figures in Hong Kong till 1971.
The figures made were Union and Confederate soldiers. Same figures with different colors. The steeds were the same for cowboys or knights. They made Cowboys, Civil War,Crusaders, Knights,and Indians.
The bases are marked Transogram made in Hong Kong. The figures were available individually or in sets. Prices ran about $2.00@ or up to $120.00 for large sets.
I was wrong thinking they were Timpo copies. This company was a separate company that made their own figures in plastic. They were also known has Playwood plastics in the US. Playwood pressed figures stopped production after WWll when plastic for figures became available instead of pressed wood and glue. Leadmen
