This is a nice clean 20/16", 1.25"diameter auger bit in usable condition.  It is not marked by the maker, but is the Jennings pattern type with double cutting edge and spur, and double polished spirals.  It is 9.5" long overall.  It has some light discoloration on the metal surfaces, but no no damage or issues effecting the cutting surface as it is very sharp and ready to use.
