I am not an expert on Pairpoint, but I have certainly seen some similar style (but neater) canes in Pairpoint paperweights. The canes do not resemble any NEGC ones that I have seen - nor do I think it is Silesian.
I understand why one might suggest Old English, but I do not recognise any of the canes. If the weight had turned up on my desk I might have suggested it could be Belgian!
A mystery piece, as far as I am concerned.
