Displaying and dating a collection

Several months ago, there was a very interesting thread about showing your collections. At the time I didn't think it applied to my dresses, suits, etc. but it does apply to my buckles.

This is a pretty little box I bought at a market in London has a glass top. This was probably the craft market when they had lots of vendors who sold items they had made. In more recent years I've seen only a few quality items.
I posted some of these a couple of weeks ago. Any help you can provide with dating would be greatly appreciated. Also, I can easily photo any individually.
thanks for your help.

 

Those are lovely

 

So pretty! What a nice way to show them off!
