"Push Key Patent Model Padlocks (Pancake)"

When the reverse of a case is not shown in a picture it is assumed to be plain unless otherwise noted.

When a depth measurement is given the measurement is taken at the edge of the case at a point where the seam is the tightest, thus rendering the smallest measurement. If a bevel is present on the case it is taken before the slope.
