Foreign silver marks?

Hi _ I have 3 glass containers, from a dressing case I think. They all have different marks on their lids. Have looked online and think they might be US or Canadian as they use the word ‘sterling’ but can’t find anything specific about them. Any suggestions/info would be really helpful. Thanks in advance:)

They are German marks. This is not my area of expertise but there are a few online sites which have German makers’ marks. You may be able to nail these marks down by looking there. The use of “sterling” may indicate that they were imported into the US.

Hi Phil - Just looked up German marks and you are right! Will investigate further, thank you! Tania
