Alto Horn GARDBAG. GREAT. This GARDBAG seems to be designed specifically for my 1889 Boston Musical Manufactory horn. The bell slips into the thick cone designed for that purpose. The velcro strips of foam did not need to be relocated because my horn is quite small compared to today's standards. It should be suitable for even the long Yamaha models. Did I mention the price? A typical price on the internet for the other bags usually exceeds twice the price. Mine was a fraction of that. WHAT A DEAL ..... !!!!!
