Camp Randall Quartermaster
Original Civil War Uniforms

Federal soldier wearing an issued frock coat.
A very young "soldier"wearing a "brand new"  dress coat and army dress hat. Note the very sharp "V"on the sleeve piping. Also notice how "high" the collar is.  As the progressed, the collars onfrock coats  tended to become lower.
Schuylkill Arsenal Enlistedman's Frock Coat (Private Collection)

Schuylkill Arsenal enlistedman's frockcoat Most likely an early war issue as the collar is 2 1/4"high. As the war went on, frock coat collars tended to become lower.
The back buttons on frock coats stayed the same distance apart (about 5 1/2") no matter what size the coat was made in.
The collar on this frock is about 2 1/4 inches high.   The coat is trimed in sky blue cording, entirely sewn on by hand, insead of the wool piping.
An enlistedman's frock coat was lined in each breast with quilted black alpaca.  There are no breast pockets in a frockcoat.   Instead, it had two "tail" pockets made of brown pollished cotton
Frockcoats had a stripe of wool hand sewn over the seam where the body of the coat meets the tails.  It runs from one end of the tail pocket to the end of the other tail pocket. (Notice the "eyes" on the back of the skirt tails, there are hooks on the front of the tail skits)
The "cording" on the cuff is sewn on by hand.   The coat has a functional cuff, held toghter by 2  1/2" eagle buttons.
Enlistedman's Frock Coat - Black River Falls Historical Society
Black River Falls, Wisconsin 
An infantryman's frock coat at the Black River Falls Historical Society, Black River Falls, WI.  The maker of this coat is unknown. It is made out of 15oz. "uniform cloth" and is trimmed with sky blue "piping" unlike the first example, which was "corded". (In doing this type of trim, there was 2 ways. The first was sky blue wool was  sewn around a cord and built into the seams as the coat is made, the second and most common was the sky blue trim was just folded into a trim and sewn into the seams) From the outside, the coat looks like a standard enlistedman's frockcoat, but has some "very" interesing features on the inside.
The right (and left) interior breasts of the coat is lined with quilted black alpacka with  brown pollished cotton tail pockets. Unusual to this coat is that both breast linnings have brown pollished cotton pockets sewn on to the interior linning. (field modification???)   Notice again, the blue wool facing covering the  seam where the body of the coat meets the tails.
A view of the left interior quilted lining. It also has a brown pollished cotton pocket sew on it.   There is "Also" has an additional pocket sewn on, where the body meets the skirt.  This pocket looks like it is  sewn on by hand, also.
t is interesting that the sleeve linning of this coat  are made of a brown plaid cotton, rather than the standard muslin.There are no maker's stamps, inspector's stamps, or size markings on the coat.  (The white tag is marked  " P.P. White, Whiting, VT".)
A good view of the brown pollished tail pockets on the back skirt of the coat.On this coat, there is a wool facing covering the opening of the pockets.   Again, notice the wool strip hand sewn on running from one end of the tail pocket to the end of the other tail pocket,  covering the seam of the body and the skirt.
Notice the piping comes to a nice point nice   Again, the cuff is functional with 2  1/2" eagle buttons. (You can also get a nice view of the plaid sleeve linning)
Finally, another "nice view"of the sky blue "piping" on the end of the frockcoat sleeve.
