The liner is beautifully tailored and is a blue satin type material with typical soiling found in tunics that were actually worn. Also, there is a lot of attention to detail even though there is no tailor's tag present. A name has been inked on the inside back below the collar which appears to be A. Guinn, but I cannot say whether or not this was done by the owner. It is not the name of the veteran who brought it home.
The shoulder boards are the sewn-in type with two silver pips along with a medical emblem affixed over silver tresse with blue backing.
