Towner for use with Bigsby B3 tremolo system, to avoid drilling holes to install. Condition is excellent, with no visible damage and fully functional. I have added an image to show this on a guitar with a Bigsby B3. The B3 trem is listed separately. Super easy to fit, replacing your tune o matic tailpiece, and using the studs to anchor in place and provide the necessary break angle for the strings. Any questions just ask.
