B&H Imperial A Clarinet. Built in the 1970s and played a lot. Fully overhauled November 2019. Bottom section fully stripped down, short through steel on F~ C / Eb~Bb replaced, key corks replaced to regain good regulation. Top section ~ G# key straightened and loose pillar fixed. All through steels withdrawn, cleaned, lubricated and reassembled. Very nice tone. I would welcome anybody who would like to come and try it out first.
