Rickenbacker Montezuma Brown

Rickenbacker's Montezuma Brown is a dark brown to natural burst finish, resembling a shaded brown found on some first-year Capris ('two tone brown'). It's not the same as the reddish-brown Montezuma Brown from 1954-1957, which was a solid color. 

In practice, Montezuma Brown is a 'more brown than red Fireglo', and its difficult to visually tell Montezuma Brown from the 80's Autumglo, or 'Tobaccoglo' as used on the 480XC...  It also varies from run to run, so its not entirely consistent.

Montezuma Brown was the 'Color of the Year' in 2003 but was used on several other runs outside of that year.
