About the Mizuno JPX-900 Tour
The JPX-900 Tour was the first Tour model in Mizuno's JPX line, a compact Grain Flow Forged cavity back in 1025E Pure Select mild carbon steel with a PowerFrame chassis stiffening the perimeter. Lofts are traditional — 34 degrees at the 7-iron and 46 at the pitching wedge, against 31 and 45 degrees on the JPX-900 Forged — with modest offset from 0.130 inches at the 3-iron to 0.102 at the pitching wedge. An unsponsored Brooks Koepka used it to win the 2017 US Open and the 2018 US Open and PGA Championship. The set ran 3-iron through pitching wedge. Lofts, lies and lengths listed are the men's standard steel-shaft build.

Finding a used set
The Mizuno JPX-900 Tour ran from 2016 to 2018 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
