Hi
I just spotted one here:
https://themusicfarm.com/collections/bass-guitars/products/taktb10lh_12060155-takamine-acoustic-electric-fretless-bass-guitar-with-radiused-fingerboard-spuce-top-lefty-slight-flaw
Grab it - it's really exceptional that one comes up for sale; this is the 3rd one I've seen for sale over the years. If it wasn't for me playing double bass (lefty of course!) I would be all over this!
regards
