can you identify these markings? Hand inscriptions on sterli

[daytonabchclarks]

Hello. I recently found this piece at auction and ithas no hallmarks nor any information about a manufacturer. A friend told me that the hand made inscriptions in the second pic that i have sent you stand for the manufacturer name pattern # and year it was made. Is that true? if not what do the inscriptions stand for. They are as follows T 2754-29.

Greetings,
Scratch marks of this type are most often incised by restorers and polishers, they don't get lost or torn off like paper tags. Sometimes they do contain dates to indicate, not of when the piece was made, but of when it was worked on or due by.
As to your friend's assertion, can you think of a plausible reason that a fine silversmith, in a factory or workshop, set up and tooled for silver work, would choose a pin point to sloppily scratch in his trademark?
