Hello Craig,
Thankyou for your post, I have included some photo's I took in the garden this morning, just natural light on a roll of wallpaper.
I hope these help.
I also forgot to put the size of the vases they are 9.3/4 inches tall.
I look forward to hearing if you can throw any light on where they might have originated.
Take care,
Nick.
P.S.
I am in the UK.
