Marrow scoop/spoon

Any help with this will be appreciated.
Id…
It seems to be silver but its a marrow spoon or scoop.
I can add more pics thanks

You are correct in that it is sterling silver. It was hallmarked in London in 1743 and has the maker’s mark TM (script). This mark is not shown in any of my references. It is similar to a mark registered by Thomas Mason in 1745 but there are enough differences for it to be accounted not the same.

Thank you.
Ive thought about washing it or some how making the marks more visible.
I thought it was j.m.
So thank you.
I didn’t have any clue to the year or date but ive never had any spoon like this one and am newish to the market of silver coins flatware etc.

Thx for your time i appreciate it and the gold and coin shops around here have no clue.
It weighs about 50.1 or 52.1 grams.
I used a scale im not familiar with but it’s heavy.

Could the maker be James Morrison?

The initials are definitely TM rather than JM or IM.
