Thanks for the replies folks - I am currently off work on holiday and once I have the boring stuff done I'll get the camera and lightbox out and take some decent pics.
I'll post a first lot of stuff that I am sure (or at least 95% sure) is Pirelli for confirmation.....then other stuff later on in dribs and drabs....at a roughly count now I have just over 100 lampwork pieces, at least 60 PWs and about 35 Mon/Vas/Strath vases & bowls.
...and a few other choice bits of Whitefriars etc.
