I received an antique rose gold pendant as a christmas present. It was bought in England. I know nothing about hallmarks, but I have spent time researching as much as possible to understand it before bothering you guys here :-). I think I've got most of it worked out, except the date/assay mark. The time it represents would be impossible for the piece.
Here is the Hallmark (if you click on it it will open up larger and be a bit easier to read):

OK, from what I understand:
1. JT&S - makers mark, probably John Thompson & Sons, London, although I have also found a John Troup & Sons registered with the Birmingham office.
2. 9 and 375 - Karat Stamp, it's 9 karat gold, and probably english gold as there is no import mark on it and it appears that english gold got the 9 as well as the 375.
3. Assay Office - this appears to be a sideways anchor, which would mean Birmingham. From what I understand they used the same marks on gold as they did on silver.
4. Date Stamp (year of Assay). This looks like a lower case q to me, which according to the Birmingham list means 1915 (although when I have put my mouse over the letter on the web site I found the list from, a note popped up with the date range 1887 - 1927, which I don't understand what it means).

The date stamp is where I come unstuck.
This piece is representative of the Third Reich, so it would be impossible for it to have been made or registered in 1915. Have I got my understand of the date stamp wrong? The Sussex office had 1933 as the year of the "q" date stamp, and that would make absolute perfect sense for this piece as the NSDAP came into power in 1933. However the Assay office mark is definately Birmingham.
Any help with this would be really appreciated, as the piece certainly has my curiousity up and it certainly would have been very unusual for something like this to have been made in England.
Thanks
