Dear chakster, To be more accurate I used Vienna as example
51 times. The reason is simple. This is the easy way to explain
how different names can refer to the same object. The so called
''co-referring names''. But those do cause confusion. Besides
we all assume that new names don't mean new products but old
one with new prices. You know how much I admire Ikeda san.
However I don't believe that that different names of those
''cantileverless'' kinds refer to different carts. My comrade Don
swears that 9C, mk 2 is exactly the same as 9C. mk 3.
Think of those Jelco (25?) headshells . There are unknown
many all the same and all with different prices. It is, I think,
our duty to our co-members to warn them when we discover
such cases. But some theory about those ''co-referring names''
may be useful (grin).
