Breuer Type 8C MkII Info Needed


Does anyone know what are the effective mass, and appropriate cartridge compliance and weight for the Breuer Type 8C MkII? Thanks.

Les Wong told me that the Brinkmann (something he also imported) was a better made version of the Breuer due to the counterweight and better manufacture. If you can find Les Wong, I also think think Peter at KJ West One in London also knows a lot about this arm (he worked with Les at Walrus Systems). I do wonder if the 8c was a superior arm to early itterations that were made when Breuer was a younger man and probably had steadier hands.
My Sumiko 800 which is also based on Breuer has 6 counterweights.
Meant for carridges from 6g. till 30 g. So, obviously , meant as
''universal arm''. I have no idea if you can get from Brinkmann
added weights? Breuer refused to deliver any extra weights. 
Contact brinkmann - their 10.5 arm is based on it - sumiko made the mdc 800 - also based on it. Both are pretty helpful.

I know from Les who ran walrus systems that they work very well with EMT cartridges
I’ve been using a Magnepan arm (7 g EM), for a few decades.      It’s had a couple Denon 103Ds (12 x 10-6cm/Dyne), a Dynavector 17D3 (15 x 10-6cm/Dyne and now a Soundsmith Aida (22 µm/mN, "Medium Compliance", according to them) mounted on it.        All tracked and performed beautifully, while none had the compliance of my Sonus Gold/Blue (50 x 10-6cm/Dyne), which I still miss.       Wish I still had one to compare with the others, none of which I’ve yet worn out.
Thanks. The MkII has the double counterweight, so can support heavier cartridges, but difficult finding exact specs for this edition.
Supposedly, but variable with counterweight changes, the Effective Mass is around 8 g.     The cartridge weight they call for is 2-8 g.     With that low an Effective Mass; a high compliance cartridge would be indicated.            https://www.vinylengine.com/tonearm_database.php?make=Breuer&mdl=8&sort=2&ascdesc=ASC&search=search&eflo=&efhi=&mdlo=&mdhi=&ohlo=&ohhi=&amlo=&amhi=&cw=
