I've had these tea glass holders for nearly 50 years, since I inherited them from my great-aunt, and they came with the glasses in them that are shown in the picture below. I have recently identified the holders as WMF (thank you, Keith from the pottery, etc. forum

) because of the ostrich mark stamped on the underside of the holders.
But my question is, would the glasses have always belonged with the holders? They are fairly thin glass, and are etched with floral swags and 'chains'. What do people think?
Thanks in anticipation for any comments.
