Would like to point you attention to my website http://HarderNet.dk
although the site is in Danish, but I think you will be able to make use of the website anyway, hopefully at some point I will have the time to make a English version.
My site is with the main interest for glass, centered around the many thousands of products produced by Danish Glassworks and mainly Holmegaard Glasswork. A spare time interest is selling second hand glass, so do you see things of interest under "GLAS SALG" (GLASS SALE), then do contact me.
As time gone by, I also have build up a bit of knowledge allong the way with the work, registrating and documenting a wide range of products fra Danish Glassworks, so is it buying or questions, feel free to contact me.
It is a spare time interest, and therefore you must not expect promt answer.
