ALL the same pitches that were available during the age of the New Wonder were available through the Artist years, excepting the Sarrusophone, C soprano and straight soprano, it seems (the F instruments and C melody were available up until the start of WWII in 1941). However, horns other than the alto, tenor and baritone were essentially "factory original" New Wonder horns with different engraving and possibly keywork modifications -- and were special order, only.
I have, at least, seen the bass in some 1960's catalogs and advertisements. Please note that the "Naked Lady" model can be broken down into.Rolled tone hole models (1935 to 1947 -- generally regarded as the best horns). Straight tone hole models (1948 to 1959). Redesigned model with wire keyguards (1960 to 1971). Same as above, but with sheet metal keyguards and different bell-to-body brace (1963 to 1971). See below for more details. The 6M design was finalized toward the end of the Transitional period and the 12M design was finalized even earlier -- though both horns did have minor keywork changes -- but the tenor wasn't finalized until about s/n 263xxx, when its bell keys were switched to the RH side of the horn. This change announced the coming of Conn's most famous series of horns: the M series or "Naked Lady" model (so named for the engraving of a nude female portrait in a pentagon on the bell). According to later Conn catalogs (after 1959), these horns are officially called the "Artist" or "Standard" model, but "Naked Lady" is the most commonly used name people use. Coinciding with the introduction of the 26M, the underslung octave key on the 6M alto is discontinued. It is brought back the next year. The "over-the-top" octave key ("New York Style Neck") appears to then remain a custom option throughout the life of the 6M. This horn is IMMACULATE original lacquer. Great Charlie Parker sound, adjustable tuning on the neck. Mu personal horn and sad to see it go.
