Grado G-1+ Cartridge - a vintage classic and NOS

I'm selling some of my classic Grado moving iron cartridges that I've been saving over the years.  I've not used or mounted this G-1+ but I included pictures to show the channels are not open so this is my best ability to illustrate and endorse its condition.  This G-1+ has what appears to be excellent balance between channels based on resistance readings.
      
As a little editorial side-note to my original attraction to Grado, I bought an F-1+ at Sound Associates in 1979 and still use it as one of my daily cartridges. I later sold Grado during the time of this classic period, or what I refer to as the Fluxbridger series (so as to distinguish it from the current Prestige line-up that arrived after Joe Grado retired).  I've tried the Prestige "Silver" and though fine sounding overall it is certainly different than my F-1+ as well as the G's and M's of the Fluxbridger era, which were Joe Grado's premier pieces other than his Signatures.  Since that time there are now Platinums, Sonatas, References, and Statements that have developed since Joe's departure.  For my own tastes (and budget) I feel the fluxbridger series embed Mr. Grado's finest work and most mature and musical expression at an undeniable value within each model of that series. In contrast to the Prestige series, which is considered entry-level for Grado today, you'd find the Fluxbridger series to have mostly nude mounted styli, through the shank styli at even the $65 range on up, unlike the glued-on (bonded) bush-mounted diamonds used in the Prestige series all the way through the Grado Gold 2.  A Grado Black sells for ~$75 while the Gold 2 is ~$260.  The F-1+ sold at $75 back in the day and it's design and performance are many levels above the Black (though I understand the Black, or any Prestige, with an 8MZ stylus is a wonderful combination) and I would speculate it betters the Gold 2 in overall performance as I believe the F-1+ stylus probably plays a significant roll in that.  Only my opinion of course but I'd venture to say it may require ~$500 or more to get the design, materials and performance of an F-1+ in a Grado today, and the G-1+ is a level up from the F.  It's all about simply enjoying what you have and for me its come down to having all the Grados I've been fond of and keeping all these years is really more about collecting than needing, so I've decided to let the extras I have of them go at this time to someone seeking the same enjoyment from them. 
      
Shipping will be by USPS Priority mail and I'll prepare the G-1+ to arrive safely, otherwise I cannot accept returns due to being NOS as well as delicate nature of the component.  If you have any questions feel free to ask and thank you for looking!  :-)
