This is a super clean antique 4-5" micrometer with both the adjustable brake and fiction ratchet features. The micrometer has over 95% of it's original dark green paint, very clear markings, no rust or damage. Still feels like a new one. Lufkin made very good quality micrometers and this is a fine example of one of the older ones. Also included is the original wood box with lap jointed corner and a nice clean slide on top. The box is very solid, 95% like new with only minor shop dirt smudges on it. A really nice micrometer!
