Rare PP6 (1972-1977)

2 rows of star canes surround a centre “P” cane. Mauve twists divide the deep blue opaque ground into 13 panels which are also filled with star canes. The hollow-ground base, the centre “P” cane and the cane formation would indicate a weight from the period between 1972 and 1977 when PP6 was phased out in favour of PP1 which, from then on, was signed in the centre.
The base bears an old Perthshire label.
