Classic Stanley 102 bevel-up block plane. This is the version with the red cap-style adjuster.
Most of the Japanning is still there except on the right side where there is wear from what looks like using to shoot end grain.
Mild patina, but no significant rust.
The sole is flat and the blade is honed, so this should be ready to go out of the box after normal blade adjustment.
It will be shipped disassembled to protect all parts from a box being kicked or thrown like a frisbee by disgruntled shipping employees.
