Karl Wiedmann Gralglas Candle Holder WMF

I bought this recently not really knowing what I was buying. I posted it on the GMB and was pointed towards Karl Wiedmann for Gralglas.

I would appreciate any confirmation .
They seem to be described as candle holders and could date back to as early as the 1930's, this one does have quite a lot of wear to the base.

This one also seems to be on the larger size .
Height 14cm.
Diameter 18cm.
Weight just under 3kg.

Thanks Roy
