Hi
Many thanks, yours certainly looks to be the same style, mine may be silver but it would have to be gold plated it has a definite look and feel of gold, this colour may not show up in the photographs. I can find no marking other than a small engraved ref number on the edge which is difficult to photograph but is similar to a watch repairers mark inside the case of a watch. I have attached a photograph which shows it to some degree.
Yours
Martin
