Allwin/Tan Sad
Tipton
Allwin (Richard Son & Allwin Ltd.) was located at Unit C1-C3, Great Bridge Industrial Estate, Toll End Road, Tipton, West Midlands, DY4 0HR, Staffordshire. Allwin is one of the smaller English brands. They may also have marketed the Tan Sad brand. The company was probably founded on January 30, 1922 as Tan Sad-Allwin Limited and existed until the 1960s / 1970s.
These photos from 2017 most likely show the former Allwin factory.
The text can still be vaguely read on the facade panels.
