Fred Rednor has it right. Harden hubs had Tecalemit grease nipples according
to a 1949 Holdsworth Aids catalog. The grease nipple thread is probably 2BA.
I've obtained 2BA grease nipples from British Tools & Fasteners

Would someone please help me remember the name for the grease fittings used on Harden hubs and similar British pieces from the 50s? A source would also be nice... harvey sachs mcLean va.
