Vintage Bruning No 3581 Black Drafting Mechanical Pencil

This German made Pencil is in good working condition, and believed to be pre East/West Germany split.  I cannot confirm this but it's definitely old.  The two Koh-I-Noor boxes show very little wear.  One is basically just the box with lead remnants and the other is brand new with a wooden tray and 6 unused, and sharpened leads.  The intricate detail and care is unbelievable.  Some light corrosion on metal parts. Comes with lead sharpener. Quality made and built to last.  and yes, the loading feature/pencil still works perfectly fine.  Please See photos for details and conditions.  Thanks and please check out our other auctions
