Grado TLZ ???

Hi,
I have a TLZ,it has not been made for 10 years,it was a $500.00 cartridge,the replacement stylus is still available for $250.00 from the needle doctor.Did you buy this new,you can call Grado for information on this.The gold is about $250.00 new.

I own a very old TLZ. It has a silvery body (probably aluminum) with a black stylus assembly. I am sure it is correct original, because I personally bought it new more than 2 decades ago. Rich, what is your question? I will try to help, but I am not sure I understand.

Yogiboy, thanks for the reply.
Lew, I am trying to figure out what I really purchased. My body is also silver. The box it came in is labeled Prestige Gold stereo pickup. The stylus on the cartridge is engraved TLZ v as is the replacement. I would like to know if all TLZ's are signature models or is the a non sig TLZ? Also what does the "v" designate? Thanks
