Dyer harp mandolin and mando-cello
What a lovely pair. I have only seen or heard of a few dozen of this form of mandolin including styles 25, 35, and 50. The mandolin is a style 50 and the mando-cello style 250. These mando-cellos are extremely rare. According to this ones serial number it is one of the first instruments produced in the whole Dyer series. This is one of the two found to this date!
