Help with embossed bottle

Hello there -

I've been searching all over the web trying to find
info on a bottle that I've had for years.

The bottle is 7 3/4 inches tall....has a crude
blobtop....and is embossed w/ the words G. RAY & SONS.
Underneath G. RAY & SONS is an embossed shield w/ the
letters G R & S....and underneath that is the word
MACCLESFIELD...the bottle is a very cool color of
olive green. On the bottom underside of the bottle
there letter A, and the numbers 987.

I myself have been collecting bottles my whole
life....I am 40 now. I have 53 very nice poisons, and
have been focusing on those as of late :)

Any information you provide is much appreciated...

Thank you
