I finally got to look at my CENTURY C50HL loader, the tag says Humpolec FL 030 HL
It also says American Jawa Harrisburg, PA, etc.
For some ODD reason I can't find the Century C50 re-badge (-:
Maybe that washed off, maybe it was never there and I just assumed it from the Century Catalog.
So, my guess is that the FL 030 A equates to the C50
and the FL 030 HL equates to the C50H
I might have the specs for both C50 and C50H somewhere, at least the glossy brochure specs.
