Here is a pic of one of my mini-Gibson boxcalls I call the "Little Henry " . I built this caller from butternut and canarywood . The butternut was salvaged from the late Walter Winterbottom's shop in Eminence , Missouri . It was cut by Walter over 25 years ago ! This one resides in the great state of Texas now . I hope it rolls some Rios this spring ! I build these alot different than the originals, it makes them alot more user-friendly than the old straight sided Gibsons. Thanks for looking !
