Vibramate V5 Short Tail

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

Where was this in the 60s

The fact that I didn't had to drill holes on my Gibsons is enough. Both my guitars now have tremolos.
