It's a B.Squire, with Hansons on the right of the piano. The serial number is K69640. So I'm thinking Kemble? It's a smaller 85 key piano.
Hansons would have been the retailers. Albert Hanson was in Huddersfield, Alfred Hanson was in Coventry.
Kembles have been around since 1911. 1929 may be the year when B Squire & Son became a Limited company, but soon after, they had a factory fire. Kemble may have taken over making them at this point, certainly by 1931.
