J. T. Forbes
The firm of J T Forbes made Highland bagpipes in Dundee from 1880 until the 1940s. In the 1930s they had premises at 44 King's Road, Dundee. Some sets of Forbes bagpipe were apparently made by other makers. Thow of Dundee and James Robertson may have provided bagpipes to the firm in the later years.
The profile of the practice chanter to the right looks conspicuously similar to those made by James Robertson.
