There is a Barnes and Mullins ZB with what the seller describes as a 'patented mute system' on Ebay UK. I've not seen a mute lever on a banjo before. Anyway, it may be of interest to someone looking for that elusive well-cared for ZB. (Oh, and my little Temlett is still for sale).https://www.ebay.co.uk/itm/125927179759?hash=item1d51d845ef:g:yroAA...
