On December 19th 1882 O R Chase of 698 Washington Street, Boston, Mass. patented his “Apollo” banjo which was said to have been constructed on “entirely new and scientific principles.”  The shell was cast in one solid piece of “bell” metal as was the bezel.

 

There was a complete range of instrument in 9”, 10”, 11” and 12 ½ ”hoop, all of which were noted for the largest number of brackets used –as many as 56 on the “Professional” 12 ½” model .
