I got set 3739 for my son last year, and just love it. I also gave my daughter
the legend versions of Black Falcons Fortress and Guarded Inn (which she loved).
The problem: the set version of 3739 is just too big to match the more
compressed Fortress and Inn--it towers over even the gatehouse of the Fortress.
Thus the need to compress the Blacksmith Shop while keeping as much of its
coolness as possible.
