I have been given a box of glass dishes by an elderly relative ...perfect in original packing labelled...Wartsila , Nuutajarvi notsjo 1793...the number is 606 6-6150-140. they appear to be tiny plates or dishes with no pattern or decoration at all . I would love to know anything about them. There are 6 in the box and I believe they were bought in the 60's., probably in Germany or Norway ..though I know they are from Finland.
