Hi Kevin,
Not one of the manufacturers listed in the 1914-1919 Board of Trade Labour Gazette....
http://www.britishbadgeforum.com/for...ghlight=Ticker so with the SH spelling I suspected either pre WW1 or 1920-22.
However, this website states the company was established in 1941
https://www.duedil.com/company/gb/00...ingham-limited the address is identical to Alan’s London Gazette link. If that’s correct then an unusual spelling for that period?
Cheers,
Luke
