This is an injection-plastic aircraft model kit.
Adapted from the Eduard website:
The Messerschmitt Bf 109G, nicknamed the "Mersu", was structurally similar to the Bf 109F-series, with slight modifications made to areas such as the wings, windscreen, fuel-tank armor, and more. This kit allows you to build two Mersu Bf 109Gs used by the Finnish Air Force.
The Limited Edition kits offer plastic from Eduard runs, as well as of those of other manufacturer’s. The plastic is then brought up to the ProfiPACK standard with the inclusion of PE sets, masks and large decal sheets, and are further complemented with other accessories such as resin details (exhausts, engines, wheels etc.), figures and/or supplementary publications. This limited edition kit comes in Dual Combo packing, containing two complete kits. They are produced with the serious modeler and collector in mind.
