Since we haven't got a canon rendition of this ship so far, I decided to take inspiration from its redesign by EC Henry.

This modest, unclassified vessel appears a few times in the Russ Manning Star Wars newspaper comics. After digitally remodeling it, EC Henry opted to christen it the Koensayr Courier due to its visual resemblance to the Y-wing light bomber produced by Koensayr Manufacturing. In the comics it's armed, but EC Henry's rendition - and thus this MOC - are not.

N.B. You will find two instructions for this MOC, one with all-light bluish gray nacelles and another one with metallic grey accents. Also, this MOC has already been uploaded to Rebrickable: https://rebrickable.com/mocs/MOC-245697/BrickRemnant/koensayr-courier/#details
