Potentiometer Overview - Alps, Penny+Giles, TKD and Vishay and more, what's your fav?

The demise of P+G slide faders is a serious issue for studio-based engineers (I believe they still supply some models, but they are made in Asia and not as nice as the industry-standard 3000-series seen in large format consoles).

However, the demise of their pots is not such a sad event. Both RF11 and RF15 have image creep at low levels (fact - test yours if you have some). They also become noisy and need lubricating if used anywhere warm. I don't think they were ever as good as the TKD CP2500, and not really as good as high-end ALPS such as RK40 and 50. In terms of electrical performance, P+G pots were barely better than ALPS RK27, but at many times the price did not represent great value. P+G was a great company and it's sad that most of the potentiometer division's lines have been culled, but I wouldn't lose too much sleep over the pots.
 
Good pictures - please load up here, because photobucket delete them anywhere.
Now a question: currently versions from Alps (RH2701, RK27112 etc.) use at the shaft for fixing not a part in the kind as to see in the first picture (btw - what is the naming therefore?).
Instead this the part looks like in the attached image (see also about
Alps Potentiometer
and go to the third picture)
and thus I must destroy and replace it through a new part in cases for disassembly.
From where I can order this part to put on the shaft before assembly, what is the english naming and which tool therefore I should use?
Thanks for advices.
