Stationery Archeology 5

Number five in this occasional series is a Staedtler tradition HB pencil stub, which I found when cleaning the dust/cobwebs/other detritus from under the computer desk.  This one celebrates 300 150 years of Staedtler pencils, dating this pencil to 1985 (see second pic). Note the joined D and T on the "EDTLER".  I definitely used this pencil at school.  Apologies for the ham-fisted sharpening as I used a knife, not a sharpener, on this pencil for a DIY job years ago.  (Edited for correct date.)
