Sterling trench watch markings.

[markr]

I have this lovely little trench watch with no name on the dial or the AS32 movement.  I tried to look up the hallmarks but with no luck besides the sterling mark.  Can any one help with the hallmarks?  Any info would help.

Sterling silver import marks

After 1 June 1907 all gold and silver watches imported into Britain were required to be assayed and hallmarked in a British assay office. They were stamped with new hallmarks that were intended to show that the item was imported and not of British manufacture. The picture here shows a set of London import hallmarks for silver. NB: For clarity this picture shows only the three assay office marks, the town mark, standard mark and date letter. It does not include the sponsor's mark, but a British hallmark must have all four marks, it is not complete and legal without a sponsor's mark

…the accompanying photo shows three of your marks- the sterling indicator, the London assay mark (though yours looks inverted) and the date letter. the fourth is a ‘sponsor’ mark…

…your sponsor mark looks like ‘GS’, likely a mark for Stockwell & Company, according to the same site…

As @rehajm said they're London import for George Stockwell 1918
