Clive,
Notice the cocking levers in the lower right of Merkel photo #3 (above) have spurs so that they function as cocking levers and trip levers in one...


To other readers...note how differently the Flues 3 piece forends have steel bits at the rear of the upper forend...nothing like a Merkel or a Griefelt...That screw in the center of the barrel bars looks as though it limits the travel and holds the ejectors.

We're fortunate to have two currently online for comparison at the same time (and to our Merkels at home)...If only someone would show us a Two Thousand dollar grade next...
