What brand of case trimmer is this?
Grey crinkle paint and a 325 are two of the features. The cutter head also has 3 adjustable blades designed to cut the length along with chamfer the inside and outside of the neck all at the same time.
The handle looks like C-H 4 D brand. The adjusting knob design looks like Hornady/Pacific.
Obviously vintage, as itis heavy duty.
