Hi, welcome to the board!
Thanks for telling us the images you have posted belong to the seller and not to yourself, I understand why you've done it, but it is against the rules here to use images you do not own the copyright on, because the board could get sued for it.
A link to the original auction is fine - (if the images are still there) that way, they are still in their appropriate context and there is no copyright issue.
It is fine to post the images if you have the direct permission from the owner to do so, but given you're asking about how right your bottle is, I don't think that they might be that helpful.
I hope you don't mind, I'm going to ask a moderator to remove them.
We will just have to wait until you can take your own pictures.
To bring out any written marks for photography, it can help a great deal to rub a little talcum powder over them with your thumb. It sits in the indents made and highlights them nicely.
There is a possibility the studio would be able to make a proper replacement stopper for you, if you were interested. You could always contact them and ask.
Ok, I've just done a bit of checking. Okra are not currently making any glass, the current economic climate has not been good to them, but the chap who started it, Richard Golding is working elsewhere now. http://www.stationglass.com/Pages/default.aspx
He still might make a stopper for you.
