***Hi.
I have been reluctant to comment as there seem so many uncertainties. The bottle referred to above, with a Perthshire certificate, is odd in that the Edition size is shown as 250 on the certificate, but 350 in Mahoney & McClanahan (which is usually correct), and it should be signed with a P1975 cane in the base - but is not. The canes in it are consistent with Perthshire canes, and it is worth noting that some Perthshire canes from the mid 1970s resemble Murano canes. I wonder whether the bowl (and maybe the bottle) are some of the one-off / trial / prototype pieces that were sold (in reasonable numbers) through the factory shop?
