(From the manufacture's catalog)
"Solid nickel silver. This exciting new creation has already won wide-spread acclaim amongst professional musicians who admire its fuller more robust tone and excellent high register. The most remarkable trombone in any band because of its brilliant quality and very striking appearance. Built in large bore .520″ with 8½ inch bell, slide and bell lock. One piece light weight slide hard chrome plated. Tone starts without effort and is easily developed to astonishing proportions."
Our example, serial number 54584, dates from 1960. IT does show some signs of wear and minor dent removal and was refurbished about 10 years ago. It comes with its orginal case.
