On his website, CJ Daley describes a jacket issued to (or purchased by) an Ohio infantryman, and shows a few original images of id’ed Ohio troops wearing similar jackets. The surviving example is mostly machine–sewn, has a 9 button front, 2 cuff buttons, functional shoulder straps and a chevron cuff, with quilted blue denim lining, and a body of dark blue kersey. Only one Illinois image (of the 17th Illinois at Vicksburg in 1864) shows similar jackets with epaulettes, though given its scale details are hard to distinguish (Figure 6). However, on the original, two types of shell jacket can be discerned: a nine button epaulette shell similar to the ‘Ohio type’ and a nine and/or eleven button type without epaulettes. Elsewhere in both CdVs and identified group images, Illinois troops seem to usually wear shell jackets without epaulettes.
One demarcation point between Schuylkill and Illinois/Ohio and other state–issue jackets may turn out to be the number of buttons – with eleven being distinctive of Schuylkill. But, with as little data as we have, the 9 button plain type may simply be a variant of the Federal government issue from Schuylkill More examinations of remaining original garments are needed to determine this issue.
