Product Description
Type Pencil erasers
Product Name Parker 51 "Long" erasers
Manufacturer and Year Parker, USA, probably from the 1950s or later as we have seen the same erasers with a different (lower) price that were probbaly from the 1940s.
Length About 7/8" long
Compatibility We checked these against a few different styles of Parker 51 mechanical pencils from both the Vacumatic and Aerometric eras. These have a metal band that fits around the eraser and supports it in the pen's eraser holder, and you can re-position the band to expose more of the eraser as it wears out. You'll need to make sure that that is the type of eraser you are replacing, as some sockets are shallow and require the shorter eraser with the metal band enclosing the bottom of the eraser. These erasers can be cut and made to fit these short sockets, but the correct eraser would have been labelled "short" on the box.
Condition New, never used. We check the erasers to make sure they have not dried out and still perform without smearing.
