i guess its a new boxing of the kits they released 3 years ago.i assume h.f.w. means halberstadt flugzeug werke or similar as the original kit had roland built long fuselage as its basis.perhaps a new short fuselage and/or new decal options at the very least. mirage put out at least 4 boxings of their earlier halberstadt cl.ii including a limited release bfw boxing which came with a collector coin.this is good news as i have the original release which is quite nice
