Lustre 801, SAEC [?], Fidelity Research, AT. There were a number of good Japanese arms; many of them made by Lustre or Jelco. The original Ortofon RS 212 was considered good in its day. I had one but so long ago I don't really remember much about it. The Zeta had a mass of 16 grams or so which should be enough for your cartridges and was a very good arm.
