Bourne, Bartley and Co
Bourne, Bartley and Co of Mayor Street, Manchester were machinists between 1838 and 1840.
Possibly built a locomotive [1]
1839 Bourne, Bartley & Co advertised 'A locomotive for sale with six of their patent wheels, now undergoing a most satisfactory trial on the Liverpool and Manchester Railway' [2]
1841 Pigot & Slater's Directory of Manchester & Salford, 1841 does not link Bourne and Bailey as a company, but gives the following information: John Frederick Bourne, engineer, house 25 New York Street; John Bartley, engineer, house 37 Richmond Street
Foot note
The Liverpool Daily Courier, 2 Sept 1882 describes the discovery of a manuscript book full of information relating to the Liverpool and Manchester Railway. The relevant paragraph reads as follows.
"The volume includes copies of a considerable number of official reports, bearing the initials 'E.W.' (Presumably Edward Wood - Ed) One of the earliest of these is addressed to Messrs. Bourne, Bartley, and Co. of Manchester, who seem to have inquired about the character of the work performed by an engine of theirs, the St. George. 'E.W.' made experiments in April, 1839, and details the results, which are hardly worth while repeating here, though the Manchester firm were doubtless rejoiced to learn that 'the engine has performed her work quite satisfactorily.'"
