This one has a P1974 on one of the canes.
Hi Amy,
it helps greatly if you include an image of the base and a side view, also state the size.
However, this is a Perthshire weight, design code most likely PP11 - in which case it should be about 3 inches in diameter.
As for the other weights: it becomes confusing if several weights are discussed in a single thread. Please, start new threads for each of the other weights.
Also another organisational note: it is preferred to upload images to this board, rather than having them somewhere else. Images somewhere else tend to disappear - which makes the entire thread more or less useless. If you upload your images here, this is prevented.
