Got my Walker back. Now has an action stop, bolt block, coil springs in place of the flat ones, 3 pound trigger pull, a cap post (to keep spent caps from gumming up the action), the arbor length fixed, and a 0025" barrel/cylinder gap clearance. Timing is spot on and it is safe to dry fire. The trigger pull is smooth and even and with the extra weight from the barrel and cylinder liners (not that the Walker is a lightweight to begin with) recoil is about non existent even with over sized loads. It is about as close to a magnum 36 black powder as you can get. Barrel and cylinder are optimized to take a .380 round ball
