I didn't find Patrol boat being PB as well. PT is motor torpedo boats,  it's listed in the "special service" (auxiliaries) section of that classification list. TB was used for the original, steel hulled and steam driven, torpedo boats;  article 8(a) of the London Treaty resurrected the type in the Japanese (Chidori class), French (La Melpomène class) and Italian (Spica class) navies, basically only the United States and British navies passed on building these mini-destroyers. ONI-222 agrees with the usage of this old classification.

PB is listed in the DANFS. Oh, it's the Suiraitei, not the Gyouraitei.

Use that DANFS with extreme care, on the first page of that list it stated that the list contains terms from 18th century to modern, that's why it contains terms like CC being command ship (that's after 1969 when USS Mount McKinley became LCC-7 instead of AGC-7). We don't know which era this "PB" belongs to, but probably not WWII.

Either way, it's never safe to follow the Americans when they appearently don't care about IJN doctrine that a non-torpedo ship can never be known as anything that contains the word "destroyer".
