Vito Clari-Tone Bb clarinet. This was Leblanc's premium plastic clarinet of its time, made of a different material than other Vitos and with slightly different keywork. .584" bore.
This one has had a complete mechanical overhaul with all new pads and key corks. Includes a hard-rubber Noblet Paris 2V mouthpiece (probably original) and ligature. The original wood-shell case is in good condition.
Yes, you can buy cheaper new instruments, but not at this level of quality. Made with pride in Kenosha, Wisconsin, these were among the best-built plastic clarinets.
