This group provided security at the exposition. First is a nickel-plated badge with a plate on the reverse having a serial number "68" along with a second small plate naming maker W&H. The following three badges are in heavy brass and these also each have a octagonal plate on the reverse naming maker W&H. The ranks indicated on these badges are: Adjutant; Second Lieut.; and Captain. These are all very well made and very rare limited issues. First examples we've had for any rank. Also see boy scout button group #608 which includes rare Jamestown expo button. Exc. to NM.
