How to identify this generation
- The pictured cavity has MP-54 lettering beside the RunBird logo.
What to notice in the specifications
- The US-site timeline labels this head 2014-2015.
- The linked chart lists a 34° 7-iron and 46° pitching wedge. Match the head name as well as those angles; equal loft does not establish equal distance or fit.
- The source range is 3 through PW; it describes listed specifications, not the contents of every retail or used set.
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.
