I've looked at it and I would like to see more pics from details. To buy a used bari is a hazzard. They can cost you a lot to get in good playing condition. Baris can be very beaten up. It can be a bargain but on the other side it can cost you another £ 600-1000 (?) to get in good playing condition. And you should keep in mind that this bari is construction from the 20's (split bell keys). From my piont of view, a Weltklang, B&S, Amati, Jupiter ... is a better buy.
Yes, the Weltklang bari looks fine. The same model as I played in the 70's. But this one seems to be in better condition. Great with a Dukoff bari mpc. Perfect for gigs and tours. Very sturdy. I played my Weltklang in a punkband. Guitar, bass, bari and drums. We all had a great time. Lot's of fun.
