Lynx Parallax Beryllium Copper (BeCu) irons set, made popular by PGA Tour pros Fred Couples and Ernie Els, back in the day.  Made in the USA!  This set contains 3 thru 9, PW, and SW.  Shafts are Lynx HM boron and high modulus graphite in regular flex.  These are "white cat" or "white dot," which in Lynx's system means they are standard lie-angle.  They're in pretty good shape, other than the SW showing a fair a mount of wear on the sole (or was custom ground, not sure), and they could probably use some new grips (see the pics!)  The beryllium copper is a unique look you don't see very often; clubs aren't made using it anymore because of the health hazards of machining the material.  You can let them go back to a natural dark patina or polish them up for a brighter coppery shine.
