Colours, size and fineness of lines do very on these bits (I seem to remember there s also a very dark variation also) - probably best to wait until you can post some pictures.
Re the books for Scandinavian glass;
20th Century Factory Glass (Lesley Jackson)
Millers glass fact file a-z (Ivo Haanstra)
are both good general books
Swedish Glass Factories Production catalogues 1915 - 1960
covers a lot of Lindstrand's production work whilst at Kosta (there are a few gaps, and there's quite a lot of later Lindstrand now coming to market which I haven't comprehensively seen covered in any book).
I'm sure others will be able to ad their own favourites.
If you're really into this, I'd also suggest keeping an eye on the Scandinavian auction houses (regular modern design auctions), and Ebay, there's enough info there to build up your own reference library over time (and on this latter point I'd recommend Smart Pix Manager by Xecute.com - a NZ firm).
