Duplex noise ratio

[Richard Moody]

I am wondering why German wire sold by APSCO is not listed in its
metric size.
Röslau piano wire is listed in sizes 12 - 23 with half sizes the same
as Mapes and Diamond Brand.
	The question is, is # 20  1/2 wire the same or different from
manufacturer to manufacturer?
