As far as I know, one of the Ikedas was sold for a time under the Jeff Rowland brand, maybe there was also a Cello version?
If Daren's cartridge (whatever the brand is) is a cantilever-less MC, it would have been designed by Ikeda rather than Takeda. I just had dinner with Ikeda last week, and he gave me the clear impression that there was so much specialized know-how in those designs that no one else would be able to pull it off.
As far as I have seen, Takeda prefers fairly conventional designs in terms of both cantilever and magnetics. I can't recall any design that he has done so far which attempted to push the technological envelope (not that there is anything wrong with that approach).
The specs that Nsgarch posted clearly look to belong to a cantilevered cartridge - the Ikedas have quite stiff compliance, and 23 x 10-6cm/Dyne is in comparison far too high.
"Copper-colored pieces" sounds like an Ikeda design - I know that Ikeda used copper plating on the polepieces (yokes) of at least some of the Ikeda 9 family.
Hope you solve the puzzle!
