You're buying the Stanley #18 block plane shown in the photos.
This plane is in good working condition and has been inspected, cleaned, oiled and is sharp.
The lever cap does have some pitting  and is missing most of its original plating as can be seen in the photos. The cap also exhibits  the Sweetheart logo and patent date of 2/18/13.
A good user plane, bench tested, and ready to use.
