We have a hard leather match case or vesta and the only identifying mark on it is what looks like a British maker’s mark. We have been unable to locate any source that provides markings on leather. This mark is 2 lions. The one on the left is full face, the one of the right is a side image. They are holding an oval object with a circle that has a + in it and on top is a crown. Does anyone know what that marking might be or where we might be able to find the information to identify it? Thanks for your help.
