The Shanks Caledonia was an exceptional mower introduced in 1895, with a lightweight malleable iron frame and handles and choice of chain or gear drive.  The chain version used roller chains, probably the first mower to do so. It was made in sizes 10-16in, with an 8-inch model also available  for some years in the Edwardian era. Shanks's 'Small' mower, made in 6, 7 and 8 inch sizes, was very similar to he Caledonia, but did not survive the Great War.  The Caledonia was still listed in 1936.
