Repaint or Original Hafner

being from the same heritage as cast iron American Flyer, Hafner also finished their locomotives with Japan Black which exhibits a very deep glossy finish.  i just looked at about 2 dozen Hafner cast iron engines and every one still has the majority of its paint with that gloss finish.  however, even a relatively large sample, which i admittedly purchased mainly for their near to excellent cosmetic condition, could not begin to cover all the varied environmental conditions associated with long term storage and though it looks as if the matte finish piece may have been oversprayed at some point in its life, i would hesitate to admit being 100% confident in saying so.

#100 Hafner cast iron locomotives with various boiler bands and wheels types (cast iron & pressed steel).

early Hafner motors with brakes (neither of which should be in your #100 locomotives) can be found with two different systems.  the early deluxe motor (brakes and siderods) used a push-in lever with a lock and spring return which activated a friction brake to the right front drive wheel itself... pictured on the right.

the later brake (shown on the left) employed a side to side moving "paddle" which inserted a pin into the governor.  be aware that forcing this lever into the braking position without the motor running has a slight chance of damaging the governor as the pin can only be fully engaged when the governor mechanism/ weight is not in the way (i.e. spinning).

Dipped or sprayed?

(in general I would expect a dip to be very old if not original )

Lots of cleaners could leave a gloss looking matte over time too.

The nooks and crannies of the under and inside of the shell is your best bet for finding clues not in print imo.
