What to check before using the reference
- The US-site timeline labels this head 1991-1993.
- The linked chart lists a 34° 7-iron and 47° pitching wedge.
- The source range is 2 through SW; it describes listed specifications, not the contents of every retail or used set.
- The head is lettered Astron Generation 2; the timeline and chart call it Astron G2.
- Mizuno’s Axis chart lists exactly the same lofts and lies from 2-iron to SW for a different head.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
