Very thorough answer. I learned something. Thanks again.

I understand !! Remember the purpose of a makers mark is so you can see who made it !! Usually it will be some form of the factory name or a known logo !! It will never be numbers unless they are a part of that name or logo !! With your vase it would have had a stick on label !! People usually remove them so ID`ing is impossible with the number of things that are exported to other countries for sale !!

Thanks for replying. I always try to identify the items in my collection hence my original question.

Many of the import vases are quite nice !! Have a couple myself !!

Thank you very much for your reply. It is a nice vase kept using for a while now.
Thanks
