Imperial Russia Order St Anna 2nd class gold civil division - Mark on ring

[PAVEL]

Hello,

Back after several months of inactivity !

Maybe someone can help me : it concerns the marks on the ring of a St Anna 2nd class gold civil division manufactured by A.Keibel (AK)

All my gold orders have on the ring either the kokoshnik mark (56 & woman head) before 1899, if I remember well, or 56 & St Petersburg crossed anchors before 1899.

I have been proposed such an order with AK on the ring without russian gold mark + ET mark (french mark for 14 ct gold applied if item sold at an auction).

Never seen that before, is-it really unusual ? The order is pure russian made with original marks under the enamel (eagle & AK).

Thanks for your help.

Regards

Pavel
