There are no maker of silver marks probably because most of these were custom made so this piece has been nitric acid tested and guaranteed. If you are unfamiliar with using nitric acid the test rub will disappear and come back bright blue when using 18k acid indicating silver.
The condition is very good no enamel losses or damage. I have not cleaned this medal because it would be difficult to keep polish off the cord and for the buyers who wish to have this in original unused condition.
