A big collection of brass buttons marked 'SR'; We believe these are old Southern Railway badges.
The buttons are marked on the back with different marks / makers mark including 'J Compton Sons & Webb Ltd, London', 'H Lotery & Co, London', 'Special Quality'
We are new to badges/buttons so only have limited knowledge at present.
You might also be interested in the 'Engineman SR' badge.
