Just to add to this, here is one
that is the same pattern as David's (having a 1-1-2-2 set up of canes between the radial twists). It confused me for a long time. I decided it might be Strathearn rather than Perthshire PP1. Recently I changed my mind, but have not yet updated the web page to say so!
A weight similar to mine was mentioned to me by another collector, and it had a Perthshire Paperweights label. General style, overall appearance, detailed pattern form ... all matched and so, with a PP label, it was settled.
For most of us, these unsigned PP1s (and same, but smaller, PP2s) from Perthshire are one of the more difficult weights to attribute. As Frank shows, there are many variations on a similar theme.
The book The Complete Guide to Perthshire Paperweights
states, "thirteen or fourteen radial twists" but also adds, "Some very early PP1s have considerably fewer radial twists and weights with larger numbers of radials also exist".
So, David, your weight may
have been made by JD - at Perthshire Paperwerweights (1969 to 1978), but not in his own studio (1978 to present). The info in Anne Metcalfe's wonderful little guide is correct and any weight by John from
his own studio will have some form of identifying cane.
