You have an Argent cartridge. What looks like a small script "s" is actually a stylized "A." The small "dot" is really a downward pointing triangle beneath (not above) the horizontal stroke. Argents were distributed by Direct Sound, which had a 1982 address of 150 Fifth Avenue, Suite 516, New York, NY 10011. An ad for Argent with this logo appears on page 127 in the October 1982 issue of Audio Magazine, although Argent cartridges are not listed in the annual equipment directory in the same issue. The October 1983 issue of Audio lists six Argent cartridges in the annual directory. They are all moving coil. They range in price from $660 to $96. The three most expensive ones have outputs identified as "0.2 mV," the fourth most expensive one has output of "2.0 mV," and the cheapest two are "0.1 mV." Recommended tracking force for all of them is "1.8-2.2 grams." Recommended load capacitance for all of them is "100 pF." The styli are all elliptical or hyper-elliptical (I have the radii if you want). Best regards.
