This is a circa 1865 pint flask, McKearin's GXI-22. The top is an applied taper band ring top. It's a pint. Nice character.
Embossed: FOR PIKE'S PEAK / (pic of man walking with cane and satchel over shoulder) // (pic of tall shaped right-facing eagle, positioned slightly right of center)
Height: 7 3/4"
Condition: Near mint - structurally perfect (no dings, chips, cracks), hardly any wear, and clean. Only issue is that it has a fleabite teeny nip off the top that you need to feel for. Great strike.
Reference Number: L113
