ordered a new Brooks saddle through a friend who owns a cycle shop, today i bolted up a 1930's Triumph rear frame and loosely trial fitted the seat

found this image of a JAP powered Chater Lea

after a few phone calls and a bit of trading, I managed to aquire this main frame section, from a 1920's Chater Lea

This project started when I was offered most of a 1929 twin port OHV 350cc JAP single, originally built for a sports road bike it would be the perfect power plant to put in a lightweight vintage special.
