Maker's Mark ID, please!

Can anyone possibly identify the maker’s mark on this bottom-stamped, 1770,
London soup ladle, please?
Many thanks if you can help!

My money is on William Grundy. But that’s just a guess, based on this:

It could also be my unidentified WT, seen on flatware 1767-1770:

Many thanks for these two replies. I was very confident that the mystery had been solved when I first saw Wm Grundy’s marks. However, the mark could, indeed, also be the unidentified ‘WT’ from the lost registers…? Hmmmm…

Tough call. I agree that the mystery WT is a bit closer to the mark, so to speak!
