1904 Touring Runabout Oldsmobile

if a 1909 International Harvester could pass for Chitty Chitty, this would be the one... the Steam Punk exhibit at the San Diego Auto Museum in full effect

that cool old vehicle in the 2nd Sherlock Holmes movie, Game of Shadows... is an 1893 Duryea

This frail gasoline-engined buggy started it all when it was driven on the streets of Springfield, Mass., on September 21, 1893. The second Duryea built won the Chicago Times-Herald Motocycle Race, Nov. 28, 1895.

 The Duryea Motor Wagon Company constructed 13 identical automobiles in 1896, making them the first American company that moved from making one car to making multiple copies for sale. Although they did not build the first American automobile, the Duryeas—like a number of other early automobile pioneers—claimed they built the first American car.

Anything that isn't gasoline probably isn't very easy to get ahold of

1920 Triumph model 550h

 Acetylene headlamp I think

 10 to 12 stone... this is flipped upside down so it's easier to see than how it's on the bike.
but when did you ever see a weight limit of a motorcycle seat?

this doesn't have a steel chain, it has a linked leather band, like the Isotta Fraschini fanbelt.
