There is one for sale on the Riverside, CA C/List. Just put in Battersby and you should find it. Guy has an interesting provenance on that item.
Just looked them up.. the aluminum man seller has one with the number 0109 and it looks kinda old.. the other bloke has 0108 and it apparently is NOS but looks like a repro / too new to be NOS to me.. http://www.ebay.com/itm/ULTRA-RARE-...Parts_Accessories&hash=item460f2df253&vxp=mtr http://www.ebay.com/itm/Rare-Batter...Parts_Accessories&hash=item2c799380de&vxp=mtr
