The B50 was produced in the 1990s and used mainly for single-frequency 50kHz operation. It was a non-valve transducer.
The retaining clevis pin enters through the side of the threaded portion of the bronze housing like the B44.
The speed insert, blanking plug and fairing for the B50 are no longer available.
