AV & Co

AV Ebblewhite established a wholesale and retail musical merchandise establishment and between the years 1901 and 1918 they sold (as wholesalers and retailers) a great number of zither banjos bearing the name of AV & Co as maker but these were made by Arthur Windsor, (Birmingham, a personal friend of Ebblewhite), Wilmshurst (of London) and Matthew (of Birmingham). 

October 2012: It is clear that Ebblewhite exported a lot of Windsor Banjos under the brand name of "Challenge" bearing all the characteristics of Windsor made banjos including; the standard Windsor Popular plain "paddle" peg head, the inlay pattern (see Barnes & Mullins as well) but most typical of all, the chromed steel friction pegs which worked reliably and well.  

These banjos were made to a price and often had very thin ebony veneer for fretboards while Barnes & Mullins and other customers of Windsor specified 5/32nd" or thicker for their better banjos.
