This is a pair of 14kt. gold, guilloche enamel, silver and diamond cuff links, The marks are on the backside of the face of the links & are identical on both. The 14K is of course gold content. The "SR" is believed to be the maker which I can not find. The real challenge is the triangle cartouche which contains an upright torch thru the center with two crossed arrows behind it. The arrows are pointing downwards. Would greatly appreciate any assistance possible with the triangular mark.The right bottom corner of the triangle is out of shape as the hallmark stamp was applied unevenly. It is a true triangle. The other link's mark was not as clear.
Thank you for your time and effort-C.
