This is K&D No. 43-350B. Also referred to as the 50B
K&D bundled this model and its punch with their top of the line Inverto 18R Deluxe Staking sets. They also sold the 50 & 50B components as an accessories..
When you see a “B” next to a K&D product number, you can count on that being for “bracelet” – an older term meaning wrist or strap watch as opposed to pocket watches.
This is a valuable tool for extracting staffs quickly and efficiently. The balance arms are protected against distortion and splitting as long as you use the bundled punch. All parts except the punch are satin chromium plated. The punch is hardened, tempered steel. The 50B, as opposed to the model 50, fits wristwatches only.
The 43-350B with its accompanying punch, 50B, is difficult to find.
You have to take care in choosing this tool. The sub-punch on the end of the 50B stake bends easily. I’ve seen them sheared off. If you attempt to take the bend out you should have agility working with staking tools. The K&D staff remover is basically worthless without the correct punch with a straight extension and clean hole for the staff. If you don’t have that, the staff will not come out cleanly. You’ll have over banking and end shake.
DIRECTIONS
Select proper hole in Staking Tool die to let hub of staff through: place balance with staff to be removed in same. Set remover over same and insert its pu!1ch through staking tool and
main body of remover. Holding punch in position over.. pivot with finger of right hand tighten knurled remover nut upwards against staking tool arm.
Stop arm of remover will swing against body of Staking Tool and prevent body of tool turning while tightening knurled sleeve. Do not over tighten this sleeve:
it is not necessary. Now strike punch a sharp blow with light hammer and staff will come
out without injury to Balance; riveting of staff simply being sheared off.
