I had a 200E 16 gauge with double triggers for a few years. Case color hardened and pretty simple line engraving. Neat gun as it also had a front articulated trigger. Kind of a purple cow as they say. Sold it to fund the Fox addiction. As far as I know the difference between it and the 201E was indeed heavier germanic type engraving. Also, not sure if the 201E was case color hardened or a grey receiver to show off the engraving. Mine was made in 1955.
