Prototype Putter - Material Test Shot - Air Force

?/?/?/? (Our best guess based on feel 3/4/0/1)  *Rare Prototype "Material Test Shot" beaded Putter, feels boxier than an Aviar3, kind of like Ricky Wysocki's new Putter.  Not PDGA Approved, most likely KC Pro or DX plastic. Embossed PROTOTYPE.           

This Innova Air Force Prototype Putter is a rare, pre-production disc marked with the distinctive “Material Test Shot” stamp on the bottom, indicating it was part of an experimental run during Innova’s plastic or mold development phase. Labeled as a prototype putter, this disc was never PDGA-approved or released for public sale, making it a highly collectible artifact from Innova’s in-house testing. With its unique tooling and limited-run nature, it offers a fascinating glimpse into the brand’s R&D process. Whether you're an Innova enthusiast or a collector of rare putters, this one-of-a-kind disc is a piece of disc golf history you won’t come across twice.
