ADC SSX IV Cartridge... Any Info Out There?

Hello all,  I just snagged the Cartridge mentioned.  I sold ADC back in the late 70's, but I don't remember this model.  I picked it up on ebay for less the $20.  The cartridge has a label on top that says "Laser", the stylus is an SSX IV, the ebay ad said it was from an estate sale, just found it in a drawer and was slightly corroded. Well,  I got it, It didn't look too bad, the diamond and stylus looked Perfect,  almost unused.  I sprayed it out thoroughly with deoxit. Cleaned it up thoroughly,  waited a day and measured the coils,  both are good and a dead match.  Cartridge cleaned up looks great.
I'm quite aware that ADC made a whole bunch of high compliance cartridges for low mass arms,  but they did do a few with lower compliance. 
Does anyone remember this thing?  Any feedback is very much appreciated. I have 3 tables at the moment,  but don't listen to vinyl like I used to and will most likely only keep one....
I also have 2 Audio Technica AT 440ML OCC, 1 brand new,   a Shure M75 brand new, a Stanton 681eee, a Grado old GF3 and way back when, we used to modify Grado's at Marcof and I have my buddy sending me one of those,  they modded out much better than the standard Grados of the day. Right now, I only listen to my AT440.
I will probably mount and sell a couple of these with the 2 tables that I sell.  I'm very familiar with all of these except this ADC. 
 
Thanks for your help, Tim
