Janis recently wrote that she has a Freeman M-100 that was purchased in 1961-62.
And Kevin sent me these photos of a clarinet stamped as H. Freeman NY that he recently restored. He gave the information that the top and bottom of the LH joint bore measures 9/16 inch. So this is a wide bore instrument, which would be great for jazz or anyone wanting an easy-blowing instrument. Given the date and wide bore, I think this would be a French Malerne product.
