Vintage 1960s/70s Strathearn closepack millefiori glass paperweight

Found this in a local op shop last week. I hadn't been in there for a day (shock horror) & in the meantime a whole lot of new (old) stuff was on the shelves. Lots of small knick knacks, many of them quite interesting. One I grabbed was this fine little paperweight by Strathearn, which cost me a humble $5.
This is a closepack millefiori on a lemon yellow ground. Original label is intact, condition is perfect.
Made in Scotland circa 1960s/70s era.
