Droplock, I don't know anything about the Heeren but it better be good because atttactive it is not. Reminds me of a Comblain (and a combine, come to think of it...maybe an old Gleaner). It seems like it would be counter-intuitive to operate, the wrong end of the trigger guard goes down. Also what is the deal with that trigger? Maybe a single set? Do they shoot reasonably well?
