Cup MS 100 India (?) Modern

[Traintime]

Placing under keyword "Julep" as one old thread has a Sterling marked sample of similar shape thought to be Indian production but of unknown maker. In this case we have maker "MS" (or "M5") over flawed numerical like mark that might read "100". It could be some form of standard or just a cataloging number. The object has obvious leopard spotting tarnish indicating some presence of silver either whole or plated (and that garlic-y smell is detectable). No magnectic response, eliminating any iron significance in the body. Metal is of thin gauge and stamp has partially penetrated the base to interior. Lip is finished by fold over, but very tightly closed to give smooth edge. I doubt stainless steel as it's light as aluminum. Brass, maybe, but hard to say. So could we be looking at pure silver body with a marking system that just doesn't betray a standard? And is India the sole possible origin?

The like-form sample actually marked "SILVER" rather than Sterling: viewtopic.php?f=13&t=12322&p=27437&hili ... 43f#p27437

Decoration differs of course.

Seems to be a lot of "T.100" stuff having no maker and being touted as 100% Silver (.999 fine) from India in the second half or last quarter Twentieth Century. One owner, second hand, claiming verified by "Sothby's" per contact (but not handled by them in auctions due to age). If this was a T.100, then it seems to be an odd-man-out case of having a maker mark incorporated.
