Crossley badge Crossley "20hp" and "20/25" cars


The Crossley 20 hp was introduced in 1909. It became the 20/25 in 1912 and continued until it was replaced by the 25/30 in early 1919.

The number made for civilian use is not known but is estimated at 2100. At least 6000, possibly as many as 10,000, were made for military use. Before about 1919 chassis numbers were not segregated by model type and are in the range up to 12000. Many ex-RFC tenders were later re-bodied as cars or buses and possibly given new civilian chassis numbers.

The engines were numbered and date stamped and engine numbers and chassis numbers were close but not usually identical. As an example, engine number 11152 is stamped July 1918.
