Vintage used and being offered for parts or repair , Kilburg Geochron time indicator model 224J . I just picked it up, and was told it was not working . I have only dusted it off, I opened the back for inspection ( the gear inside the back for the motion was not aligned properly, and it was a little dirty inside ) . I see a small scuff mark down and to the east saint George island in the antartic and there is a ding on the top edge . The surface of the enclosure is a brownish cover over the aluminum . Some images make it look like it black . It is not black Needs quite a bit of cleaning and some restoration At my own choice I will ship by either UPS ground or fedex ground.
