Check the length of the removable tip on the cocktail shaker. I've never seen one like that. Anyone out there have any?

Upswept Pipes for Early Triumph's

1947 ad for Custom Upswept Pipes

This photo looks to be from the late 40's. Gall's Cycle Shop Upswept pipes and dig the scallop job on the tank. Very similar to what came from the factory 20 years later.

On the track circa 1947 with small diameter open cones.

Early 60's custom street bike. Barbarions MC from the Four Aces Cycle Website

The later MCM product looks like a exact copy of the Gall's Cycle Shop pipes with the big sweeping bends. The Superior brand High - Flow pipes that came out around 1950-51 had a much tighter bend coming out of the cylinder head.

1946 Senior Manx Grand Prix Winner

In 1946 Triumph wins the Senior Manx Grand Prix at the Isle of Man on a highly specialized Triumph twin. The engine was based on the wartime generator set made by Triumph with a all alloy cylinder and head which was a first for Triumph motorcycles. It is also equipped with the new sprung hub rear wheel that is not widely available and still considered somewhat experimental at the time. This machine is used to advertise the 1947 line up but is not made available to the public yet.

New for 1946 - The Triumph Sprung Hub Wheel

Interesting article by Triumph man Ivor Davies. Seems like every book out there about Triumph's has the same old lines bad mouthing the sprung hub. If you just consider the objectives of the design, including the fact that it was meant to be a bolt on suspension for existing machines and for new models without abandoning the rigid frame, the old spring wheel comes into a new light. How's about all the races won by bikes with Sprung hubs? Standard equipment on the GP model to be released to the public in 1948. Plus it's a sweet looking piece of engineering!

Early Aftermarket Seats - Pre Bates era

First type circa 1946 look like couch cushions. Ugly, but probably comfortable.

A slightly later style from 1948, still huge but some nicer lines. Must have used some really strong springs in the back to support both rider and passenger!

Here's a neat dual seat from 1948 with Telescopic Tube Mounting.

A shrouded telescopic spring solo seat setup with the grab bar appearing to come off of the pillion. I wonder if any of these seats with shrouded springs have survived?


These sprung pillions circa 1948 would go nicely behind a Lycett saddle.

JoMo gets it right. The Walker PSS2 from 1948. Very close to what Mr. Bates would be offering in the early 1950's.

Country Road Racer? Stripped for racing with no lights, but looks like there's a license plate laying flat against the back fender.

The front wheel looks huge on this racer circa 1946. At least a 21".

The same bike in 1947 with telescopic forks.
