Early STC transistors left to right: The 3X/101N prototype point contact transistor was released in 1954 followed by the TP1. The first STC junction transistor was the 3X/302N which was followed by the TS series such as the TS1 shown here.

This is the most comprehensive transistor manual on the web but note this is a 13Mb download. It was published in 1960 and covers many international types as well as the familiar Amercian 2N series. This manual is part of the website of Francesco Piva who acknowledges his associate Franco Sassuolo for much of the historical electronics material on the site.
