Hi Michael. Thanks for your comments. Of course, you're right. A second look reveals just what you are saying. A little too long, and no taper. Needs to be closer to my own detail above, in red.

Fortunatly, that will be an easy fix. Thanks for your keen eyesight.
By the way, the photos of the lock you posted above: That looks like it was from a Swedish or Russian Snaplock? Thanks, Rick.
