The article attributes the 1930 purchase to an institution that did not yet exist under that name.

JPMorgan Chase’s official corporate history states that:

• "In 1955, the Bank of the Manhattan Company merged with Chase National Bank ... to form Chase Manhattan Bank."
• In the duel-history transcript on the same official page, "The pistols survived and in 1930, the Bank of the Manhattan Company ... purchased them from the Church family."

Therefore, saying the pistols were sold in 1930 to the Chase Manhattan Bank is anachronistic and incorrect. The purchaser in 1930 was the Bank of the Manhattan Company; Chase Manhattan Bank was not formed until 1955.

This clause gives a specific founding year that does not match standard historical accounts.

• The U.S. Senate’s official party-history page says organized political parties developed in the U.S. in the 1790s, and that supporters of the Washington administration in 1789–1791 were merely "pro-administration" figures who would eventually form the Federalist party.
• HISTORY similarly explains that the Federalist Party emerged in the 1790s and became publicly well-defined only later; it explicitly says the party "cannot be considered the lineal descendant" of the pro-Constitution "federalist" grouping of the 1780s.

So while Alexander Hamilton was a leading Federalist, saying he had founded the Federalist Party in 1789 is historically inaccurate.
