Two-piece Block "I" (Yellow & Red Brass)
Solid, medium width block 'I' on a plain field. Typical examples
(usually of yellow brass) have a slightly raised rim, 'puffed' rim
examples (usually of red brass) seem to be a Western variant.
Brass/copper backs occur on Virginia made locals, while tin and iron
backs occur in all theaters. Backs were usually not marked, although
brass examples often had some variation of "E.M. Lewis &
Co. Richmond VA."
Coat size (22-23mm diameter), and cuff size (16mm)
Various, probably throughout the Confederacy, though brass/copper
backed examples were made by E.M. Lewis (Richmond) who also
manufactured other block letter branch of service buttons. Many
buttons manufactured by Lewis were not backmarked.
