Hi all
whilst trying to do a bit of research on a couple of caithness limited edition paperweights (and not coming up with a great deal), i stumbled across this fab site. It has lots of info on mainly caithness weights but also includes selkirk and a few other designers. Its not a massive glass site but certainly has some good useful info, with dates and edition numbers including actual editions numbers produced designer and so on.
Hope it helps
michelle
