Skillet Marks

Identify a vintage cast iron skillet from its marks

Turn the pan over and tell us what you see: the wording, the numbers, the heat ring. Skillet Marks compares those clues with a sourced reference library and shows which makers and date ranges fit, what supports each one, and what is still in doubt.

How it works

  1. Look at the base. Hold the pan bottom up with the handle at 6 o'clock. A photo helps you keep track of where each mark sits.
  2. Enter the clues. Copy the wording exactly and note the numbers, ring and handle. Skip anything you cannot see clearly.
  3. Review the evidence. Each candidate lists what fits, what does not, the documented date range and the next photo that would help most.

When the answer is “we can't tell”

Plenty of old skillets carry no maker's name, and some cannot be attributed by anyone. When the clues are thin we say so and suggest what to check next. Date ranges come from collector references and period catalogs; where those disagree, you see both.
