Oh, I will try to remember to look out for it when I am looking through books in search of late period Finnish stuff though. I need to do some research on late period glass trade and what went where too. I know there was a lot of trade from Venice to various places, and of course cullet got shipped to Venice, but I want to see what I can find on other areas ordering, shipping, and trading glass and finished vessels. Nothing like really old paperwork and receipts! ;-)
