This rings a bell, Kapitan. IIRC the US tried to develop a medium piece for several years but it had so many teethig troubles that they gave up. I think this was it. I'll try to find out for certain.

Found it. "America's first QF gun was an Erhardt design with modifications, designated the 3 inch M1902. Erhardt built 50, and production was continued at Rock Island Arsenal. A 3.8 M1907 was developed at Rock Island, followed by the 4.7 M1908, but the 3.8 was a failure and the 4.7 produced only in small numbers." - Ian Hogg.
A new design was drawn up in 1912, to be the split-trailed M1916, but there was so much tinkering (and so little input at the design stage by the actual soldiery) that the first one wasn't completed until March 1918. By the end of the year 249 had been delivered, but the Artillery were dissatisfied with the Model and much preferred the French 75 with which they had been equipped.
