In order for me to properly assess what you have I will need to know the height and see images of the vases along with a clear, in-focus close-up of the mark (if any).
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
There may be an +Add Files button or if there is a toolbar with a paperclip icon showing above the box where you type in responses, then follow the steps on this link for sharing photos:
You can try emailing your images to *****@******.*** and write “For Nora/Antiques” in the subject line of the email.
Photos sent by email do not arrive to me directly nor instantly, they get forwarded to me by admin.
I received two images, thank you. Are these marked at all on the underside?
Thank you for checking for me. I am not able to confirm the age or makers of your Japanese mixed metal vases. I will opt-out here and open your question again to all the experts at no additional charge. If someone knows the answer, they will respond to you here. You do not need to re-post your question.
I do hope you find the information that you seek.
I have not received any images. Did you email them? Here is a link to tell you how to send them. http://ww2.justanswer.com/how-do-i-send-photo-or-file-expert
