Does anyone know how to determine manufacture dates by serial number for a 12 gauge double barrel? I have serial number 21340. Thanks

Janssen was in business from the 1890's until about 1957. The best way to date their guns is by changes in Belgian proof marks and inspectors stamps and date marks applied to them over the years. There are several sites that list Belgian proof marks; they came be found online with a search engine like google.
