I quite understand the difficulty of selling niche left handed basses John and yours is lovely. I think I paid Pete the Fish about £1,200 for my five string (with gold hardware), albeit in c 1990, so I suffer a bit at the sticker shock of what Wals go for now.
For the record, I thought your bass was one of the best set up I've ever played, and it sounded just like a Wal should!
