Just from the photograph so I am quite prepared to be wrong. That top leaver looks like it has been cut from a plate of steel with no rounded edges, also with that notch being cut to allow the leaver to pass the hammer and with the engraver not following the curve with his border line this is far below the Reilley standard that we expect. I feel that is an after market alteration may be for some physical problem of the owner further down the lime.

The only lessons in my life I truly did learn from where the ones I paid for!
