For sale is an original USA-made 1960s electric/acoustic guitar capo by Hamilton.
 
As used by many of the greats, an effective capo that saw through many people's guitar careers during the 1960s.
 
Interestingly, I believe Gibson used these exact models (re-badged Gibson) as their own Gibson-branded capo during the 60s/70s.
 
Would pair wonderfully with an original 60s/70s vintage guitar for an authentic aesthetic.
