lovely bit of metal, very well machined 
only 2 stars given as it would of been great if somewhere on the internet or thoman it said somewhere that it was not compatible with a b50 bigsby, I know it only says b5 on the description here but really who would of thought they had different hole spacing b50 and b5 ! 
as it is I drilled it out and mine fits, although I only used it as a spacer and screwed straight through it onto my guitar 
 
so,,, not compatible with a b50 be warned
