Sort of unknown hallmark

[Nick56]

I have a ring with what looks the Charles Horner hallmark, but it has PLAT stamped on it. The PLAT is the other way round from the hallmark.
I have photos, but cannot see a way of attaching them.

Hi,

Welcome to the Forum.

Your question cannot be answered without the required images. The below should help you:

and: http://www.925-1000.com/forum/viewtopic.php?f=5&t=42199

http://www.postimg.com is recommended. Embedded images get a far greater response than just posting links.
