September Parts: 1960s Bigsby Aluminum Archtop Bridge

This is an original 50s/60s, aluminum Bigsby "rocker bridge" so-called because it has angled "feet" on the saddle topper that "rock" gently with a Bigsby whammy's movement to keep a guitar in tune. It's compensated for a wound G string. I picked it up in trade for other parts and now it's available. I simply don't know what to use it for!

A rosewood "foot" was added so it'd conform better to a guitar's top sometime in the past. It'll probably remove really easily... but why? It'd be useful for retrofitting to whatever guitar this'll end up on.
