Thanks Adam, but it doesn't really help, unless we already know what features can identify a particular lampworker. In most cases the lampworkers are never identified.
All most folk (myself included) can say, is that those weights, having a JD signature cane, were made by John Deacons but the lampork ... not easy to tell. There may be folk who can recognise the elements, but I am not one of them!
However, it's interesting to note the different forms of workmanship across the weights, both in the lampwork and the setting in the weight. My own view is:
1 has good work and setting
2 is quite poor, with parts not connecting as they should and even the sig cane is at an angle
3 is ok but again the sig cane loses out
4 this is best of all, in all respects
5 hmm ... what's that central flower doing ... wilting? And the red "leaves" of the pink flower don't seem too well balanced
6 this is ok but lacks something I can't quite identify
My comments are based on my perceived quality of the finished article and my personal tastes. Even the poorer examples take skill to produce.
