I have a meerschaum Swedish lap pipe that has a maker's mark (CGS), an early representation of Saint Eric for the Stockholm mark, 3 crowns for Sweden, and the remains of a date that appears to be intaglio stamped. I believe I see the top of the numeral '4' to the right, but the letter to the left is more difficult - it looks like the top of a rounded letter, so maybe 'C' or 'O' or 'Q'?
I'm specifically looking for the following information:
- date range for this particular image of St. Eric
identifying the maker 'CGS'
determining the date
