There is a lot of confusion about Graflex film holders. There is the Graflex holder distinctly labeled as such, which fit the Graflex (not Graphic) back on the Graflex SLRs and press cameras equipped with a "Graflex" back. These holders have a groove down each side and a groove for a light trap, as opposed to the ridge you see on other holders. The are a bit larger in size and fit nothing else. Then, there are the Graphic holders. These fit everything else. They were, and are, made by any number of companies. Lisco and Riteway (same company) are two of the most well known. Graphic style holders will fit your camera, no matter what the age, brand or material they're made of. Personally, I prefer the old wood ones. I've never had warpage problems. They're not a static dust magnet like the plastic ones. I've had more warped plastic holders than anything. If you prefer plastic, don't leave them where they'll be exposed to excess heat. That will warp them.
