A full set of 19th century Russell Jennings 'type 5' bits, 4 to 16 by sixteenths, 13 bits in total. Manufactured between the co-partnership of 1885 that made it 'R Jennings MFG Co.' and 1900 when tang stamping ceased. Overall condition is superb, there is a little pitting on the shank and flutes of the 9/16", but other than that no significant damage or wear.
