What Country is this Hallmark?

by Carolyn
(Canada)

I have a 9ct gold wedding band.

The markings from left to right are...
-T&S
-a right pointing arrow surrounded by three markings shaped like mushrooms lying on their side. The arrow points to one of them and it almosts looks the fist of a hand punching toward the arrow, this image is inside the shape of a hollowed out D with a point instead of a rounded front.
- a 9 inside an rectangular octagon
-375
-a Q with a line at the top and the bottom of the O
Can you tell me what country this is from and what year it might be.
Thanks...
Carolyn
