I restored this clarinet with a deep cleaning and re-padded.  It has all new pads and corks, except for the lower to bell.  Wood is solid no damage to it ever or any former repairs.  All metal is excellent.  Original case is very worn and a new one would be best.  But the wood is sturdy and brass hinges solid.  Please see pictures uploaded.  I am thinking that the serial number is from 1955.  A sweet spot for this big bore clarinet.  Was once told that the mid 50's was a very good era for clarinets.  I did the work on it so if you have any questions about some aspect that cannot be answered by looking at the pictures please email. No mouthpiece is included.
