The Messerschmitt Bf110 was designed as a 2 seat heavy fighter to act as an escort fighter and bomber destroyer. Although fairly fast and well armed it was clumsy compared to single engined, single seat fighters like the RAF's Spitfires and Hurricanes and proved easy meat for the RAF fighters. The Bf110 was used in other roles, such as fast bomber, ground attack and later as a Night Fighter.
Eduard are a Czech based manufacturer famed for their model accessories. They have in the last few years released a successful range of kits. Their Profipacks contain a kit with several marking options, along with a Colour Zoom etch set, Canopy Mask and a full colour instruction booklet. This kit is made from injection moulded plastic but is very complex with weapons bay and cockpit detail and would suit an experienced modeller very well.
There are markings for 4 different planes: including a night fighter version.
