Duplex forks
‘Compression rear forks’ – later known as twin chain stays and seat stays
Oval top tube (7/8″ wide by 1 3/16″ deep)
Handlebar swivel system with coaxial clamp bolt
Seat pin with coarse threaded axial bolt allowing the saddle clamp extension tube to be mounted either before or aft of the seat pin

THE HENDEE (INDIAN) CONNECTION
The American company Hendee & Nelson, precursor of the Hendee Mfg Co, who made the famous Indian motorcycles (and, later, bicycles), imported Centaur bicycles from England to sell rebadged as ‘Silver King’ in America.
In the illustration below, compare the old-style 1897 Centaur frame on the left with the Centaur-framed Hendee Silver King on the right (one of few survivors, this one owned by Steve McQueen and sold at auction after his death). By the time this model of Silver King went on sale in the USA, Centaur had introduced their new frame style, perhaps one of the reasons they sold the older style stock of Centaur frames to Hendee.
Centaur had previously sold outdated Centaur frames to Hendee in 1894…
