Identifying the right model

• TP-Z lettering sits above PRECISELY FORGED on a plain muscle back, with a Mizuno wordmark toward the heel in the timeline photo.

What to check before using the reference

• The US-site timeline labels this head 1990-1994.
• The linked chart lists a 36° 7-iron and 48° pitching wedge.
• The source range is 1 through SW; it describes listed specifications, not the contents of every retail or used set.
• The timeline shows the same photo and chart three times: as TP-Z for 1990-1994, as TP-Z for 1995-1996 and as “TPZ Cast” for 1995-1996. The photo reads Precisely Forged, so this record is filed under the first TP-Z entry and the cast version is not separately established.
