Assistance Identifying an Ikeda Cartridge


Trying to figure out which cartridge I got here, came to me on a Well Tempered Reference turntable.. 

Its an Ikeda with no cantilever, so one of the earlier generation cartridges I believe. It is that gold color that the 9TT is, however where the 9TT logo is there is just a kanji character. 

Vinyl engine has about 6 to choose from, but the pics are black and white and do not show the side of the cartridge where the logo is. 

Anyone got an idea which one this could be? Like I said looks exactly like a 9TT in color, but different logo and no cantilever. 

Thanks!

Also, "kiwami" is the kanji on the side.  9 Rex doesn't have any meaning, so maybe only the model number.

this is what you mean ?

I think it’s just the same cartridge Ikeda made for Jeff Rowland for USA

IKEDA 9 Jeff Rowland (Limited Edition):
Recommended tracking force: 2 grams
Frequency response: 10-45,000 Hz ± 2.5 dB
Frequency response: 10 - 45000 Hz
Output voltage: 0.18 mV 0.18 mV
Cartridge weight: 16 grams Own weight 16g
List price $ 2500

some seller mentioned that it’s probably the same or nearly identical to Ikeda R from 1989 or REX from 1993 






I sent a photo of the cartridge with the kanji label to my son who lives in Tokyo and is a scholar in Japanese.  Here is his response: "I think it says “Tsuji” which is just a family name. I can tell you it has no functional meaning in terms of what the cartridge can do. It’s also so roughly written (like a signature) that I’m not 100% sure that it it is the character for “Tsuji”'.
I hope that helps someone.
