Made at Pirelli's Potters Bar works.

75mm 3" high.
68mm 2¾" high
43mm 1¾" high

Presumably above are sizes 2 through 4, No. 1 being the largest.

Mostly designed by Edward Robbins, a scientific glassmaker who later emigrated to Canada and continued to create lampwork figures in a Mall.

All of the figures are shown in the Glass Zoo and mostly with multiple views and examples of actual figures. On request, I will add colour examples here but otherwise just use the catalogue images here.
