This is what I have on Ohio. Before the Regulations for the Military forces of Ohio was published in 1859 there is limited information concerning the uniforms of the Ohio militia. Even after the 1859 uniform regulations came out some militia companies did not switch to the required dark blue frock coats, sky blue trousers, and tall uniform cap. The 1859 uniform regulations also called for sky blue jackets for fatigue wear.
Prior to the 1859 uniform regulations the Cleveland Light Artillery are said to have worn; "The Cleveland Light Artillery had blue coatees trimmed in red and sported black leather helmets of antique pattern." (p.1084,Frederick P. Todd, American Military Equipage 1851 - 1872 Vol II, State Forces).
The Cleveland Light Artillery reformed after the Civil War in 1872. "Double-breasted blue tail coat with buttons in pairs, sky blue pants, both trimmed with red; leather helmets, brass trim, red horse hair plumes. In 1859 armed with 6-pdr bronze guns (p.1095,Frederick P. Todd, American Military Equipage 1851 - 1872 Vol II, State Forces).
