I have the twin to that press but in a four-station upper and lower die plates version.
The toggle links are somewhat skimpy (compared to an RCS Rockchucker) and even when using the center station (greatest support) for full-length rifle case resizing, it is springy and lacks the mechanical advantage for efficient use. It is definitely not strong enough for bullet swaging or case forming.
For my purposes, it works fine for loading pistol cases. Carbide dies, expander/decapper, powder measure, and seater/crimper stations make it suitable for manual progressive reloading of pistol ammo.
Cleaning that thing would be easiest if you know someone with an automotive parts cleaner machine. Lacking that, brushing and wiping with paint thinner soaked rags would be best, followed by spray lube and detailed relubrication of high friction points.
C-H was a popular reloading press and accessory maker contemporary with Lyman, RCBS, Pacific, Ohaus, Redding, etc and WAY before Dillon was established. They are still good, although slow, basic machines.
