Cincinnati introduced their first tool and cutter grinder in 1889 and have been building them ever since. By 1930 their standard model was listed as the 11/2, this being replaced in 1931 by the No. 2., a machine that was to become universally popular in markets world-wide. Built in both the United States and the United Kingdom, in the Company's Birmingham factory, it was to remain largely unchanged during its production run. However, the various sales and technical specification catalogues produced over the years do show a number of changes were made to both the machine and the range of accessories. Hopefully, the pictures below, and on the following pages, will give a near-complete picture of the No. 2 and its numerous attachments.
