|Make:||Chickering & MacKays|
Mr. MacKay and his son (hence Mackays) partnered with Chickering for a time. The elder Mackay was lost at sea during one of his many trips to distribute pianos and come home with rare hardwoods for the factory.
Somewhere between this piano at #3983 and the following piano, Chickering & Mackays #4723, Chickering went to the full plate. Have a look at the differences. The iron showing in this picture is all there is in this model.
