Need parts for Solomon Solder Station

A friend has a Solomon SL-20 Electronic Soldering Station. It has an SL-1
iron with a broken tip. He obtained it from a local company that went out
of business.

Searching the web, it appears that Solomon is popular everywhere else in
the world, but not in the U.S. Does anyone know of a U.S. source for
Solomon parts?

Or, is anyone familiar with Solomon, and know if there is a commonly
available tip that is compatible?
