Simple box chain - Looking for Maker Info.

[TLM68]

Hello folks, me again...

If anyone knows the mark on this and can let me know, that'd be awesome. Thing is, I don't know if makers typically mark their work inverted to the 925 or if the marks are usually right side up, if using the 925 as orientation. So, I am not sure if this mark is MM or WW..





Once again, any help with this is appreciated.
TIA,

Tammi

No photo left, just another 925 MM unanswered...Postwar German origins with a suggestion of where to search for the maker...a stretch, but you never know: viewtopic.php?f=15&t=26821&p=65134&hilit=sterling+mm#p65134

Thanks for your response. I may never find out for sure, but if I do, I'll post it here.
