Todd's, "Military Equipage 1851-1872", in the three Vol. set' offers in vol. 3 some very good information on Naval Uniforms up to that point in time.
Little attention was given in Nav. Reg. to enlisted uniform regulations until 1866. By tis time, the Naval service was being down sized.
CSN Uniform Reg. published in March of 1862 offers some limited description of enlisted Uniforms based on the 1851 USN Reg. Changing the color of the Uniform from blue to gray.
It is important to note here that during these early time periods, most sailors made their own uniforms from stores aboard the ship, and that most ship Captains regulated the uniform of the day.
British Naval Uniform History of these early years may not be a bad place to check?
