I've got one of Bruce Cobb's treasured parts bins and need to sell most of it.
First off is an 1851 dated Cadet lock with all original parts. It shows some corrosion and light pitting but overall is a good working lock. I'm asking $600.
Next is an 1853 dated Cadet lock with the half cock broken on the tumbler and missing the sear. The tumbler can be repaired by a competent gun mechanic. Asking $350 for this one.
Last is an original 1851 Cadet mainspring. These are as scarce as hen's teeth. Asking $125 for this.

PM me if interested. More parts to come later.
