A reproduction of superb 86-page Boley lathe & watchmakers' tools catalogue is available: e-mail for details
Surprisingly common - well, two turned up within a month of each other during 2009 and a third in 2012 - this G.Boley watchmakers' lathe is believed to take 6.5 mm collets. Stamped "Patent G.Leinen", the bed had a semi-circular base but a triangulated "bevelled" top section. Advertised alongside contemporary and very successful WW and "Geneva" models it was not a design that caught on and vanished from later Boley publicity material. The lathe has also been found in badge-engineered form with one sold as the "Telco" by Bannister Bros. of Hockley Hill in Birmingham, and at least two others, whose details are uncertain, in Europe.
