Sheaffer Ballpoint Widget - Brass adapter widget for Stratowriter ballpoint pens. Turn your early Sheaffer Stratowriter style ballpoint pen into a working pen again! Early Sheaffer Stratowriter ballpoint pens used a large aluminum tube cartridge that was discontinued in the early 1950s for a short period of time, Sheaffer made brass adaptors so that the current style BP refills could be used. We now have newly made solid brass Sheaffer BP widgets so you can turn your older Stratowriter BPs into working pens again.
