I didn't have Bivin's book at the time, but had a mentor who showed me some lock inlets he had done so that I knew what I was shooting for.

There are some glaring errors that are obvious to me. I posted this so that others can see and compare the difference between average work and the best. The more we see, the easier quality is to recognize, IMO.

Thanks for you positive comment, Steven. That makes my day.
