[Austin W Hogan]

I examined twelve Parker hammer guns of serial range 1- 159 thousand.
My initial reading of your post suggested that there was axial wobble of your right hammer; that is the hammer moved around the axis of its rotation.
Your later post indicates that the wobble is at a normal angle to this; that is the hammer wobbles left and right with respect the axis of the barrels.
Two of the guns I examined with s/n less than 2000 had non rebounding hammers and essentially zero hammer motion with the hammer down.( or in any position)
The remainder had left - right motion when down, but in the rebound notch. Interestingly all had more right lock wiggle than left lock wiggle. Re engaging the rebound notch lessened the motion.
Try this; remove the barrels so you can see the breech face; do the firing pins show? Put a little pressure on the back of the hammer and pull the trigger. The firing pin should now show. Release thumb pressue and trigger; the hammer should now return to a point clear of the firing pin, and the firing pins will retract into the breech if you have rebounding locks.
I have never looked at this before and never heard any one speak of it. Apparently a little clearance is necessary to allow the rebound notch to engage.

Best, Austin
