A small plastic strip is supplied to make the sliding rails for the original hatch on the top fuselage.
Note Vokes filters are included as most if not all of these aircraft operated in the middle east at some point, however if you can find references check them or make up your own mind. Note all parts are shown in black or in brass on assembled model.
Please note decals for DWI aircraft are available on DK Decals sheets 72063 and 72069, one option on either sheet.
