Anyone Recognize This Pattern Among Fakes?

Sorry I missed this Albert - the blooms are zinc, they occur when the surface of a cast object cools in air. Zinc has a very low boiling point and solidifies rather rapidly. It is a feature commonly seen on cast counterfeits made in the 1930s.

The metal is often called "pot metal" because the composition varies so wildly. So while there is no standard formulation or density zinc the primary component is 7.13 in density. It was used for casting of many different types of products in the 20th century because it is readily available, cheap and melts at a low temperature.

It is a perfect material for a forger. Drawbacks include the rapid solidification of the component zinc which can form a bloom on the surface and also the fact that electro-deposition onto the surface often chips away because the surface is not uniform and some of the metals used in the alloy corrode easily under certain conditions.

Pewter and Pot metal can look somewhat alike. That is in part because both alloys may contain many of the same components, just not the primary constituents.

If tin is a constituent of the Pot Metal along with the zinc then the tin itself can form blooms. So confusion is quite possible.
