WH & S Angle Plate?

[shadespast]

Hi there,
I think this WH stands for Wiliiam Hutton? I've searched and searched trying to find out just what this "angle plate" means to no avail. Also I can't find what the squiggly mark in the center of this means.

Thanks for looking,

Yes, it is William Hutton and the other mark does not mean anything in particular, except perhaps to Mr. Hutton, who used it in nearly all his marks. I have not seen the interesting "angle plate" before, but suspect it is similar to the US "sectional plate" where a heavier layer of silver was plated to those points which wore out fastest.

Interesting. Thanks so much wev.
