Need help to decipher hallmark / brand

[pnc75]

Hi All,

Back again, this time as title ^^^^ says:

It's on the back of a brooch from the same estate as the previous enquiry and is in the shape of a wishbone with a pearl at the end. I've tried googling but to no avail. 

Again TIA for any help.

STLPL8 ?

Sterling plate??

A ' hallmark ' - will give you - who, what, where & when - this is stamped.

Probably plated.

Could be. Thanks for trying to help. Would they have done that sort of abbreviation back then? (I'm not saying they wouldn't have, I'n genuinely asking, as I have no idea! 😃) 

I've enlarged it as much as I can on my phone & still can't work it out!

I'm going to do another Antiques Road Show - gawd - we are still watching from 7 years ago.

But - you have only brought in a part of the piece- really difficult with guessing the bit you left at home.

Show us the whole. lol

It looks like this but isn't in good condition. Not ebay listable, I'm pretty sure
