I regularly receive messages asking for the history of individual pianos made by Hallett and Cumston. Regretably, whilst I know the history of the Cumston family I can’t do piano histories! http://www.cumpston.org.uk/#/hallett-cumston-piano/4535432388
The latest enquiry is from firstname.lastname@example.org who says
‘I live in Florida,US and I have a client who has asked that I find the history and worth on a piano he has. Built by Hallett & Cumston for a A. Stankowitch.’
So if any piano buffs are reading this and they know the answer do let me know!
