This is one of my pattern maker's planes. (The other is pictured
). It has eight soles
and eight Stanley Sweetheart blades.
Screws in the soles engage the keyhole slots shown here.
One is near the knob, the other in the front of the tote.
The bottoms and blades from left to right are marked 15, 12, 8, 6, 5, 4, 3, and 2.
I also have a power tool
for making core boxes.
