Here is a nice example in brown Lahn. Yes, it really is a Sheaffer.

This is another Sheaffer Sub-Brand, WASP Vacuum-Fil, in Lahn Green
Clearly, these Sub-Brand names had nothing to do with the filling systems used in said pens
I don't think I've ever seen a Lahn pen that wasn't lever fill.

Lever fillers generate vacuum effect as much as plunger fill and so forth. All end up with lower pressure inside than out allowing ink to travel in.
