A. M. McPhail

A. M. McPhail was a Boston piano maker founded by Andrew M. McPhail in 1837, starting with square pianos and later making uprights, grands and player pianos in fairly small numbers. It was incorporated as the A. M. McPhail Piano Company in 1891 and moved its factory to Waltham Street in the 1920s. The name later came under Kohler & Campbell and was used until the late 1950s.
