You can retract your gear but the statement was just fine
I agree with mexchiwa on macgiver's quest pic, it looks like a Tu-2 engine installation indeed.
The engine shown would either be an R-2600 or an M-82, the colors indicating that it's the latter (typical "Brilliant Medium Blue" underside and "Light Sand-Brown" on the upper side of the cowling).
M-82 would potentially be found on Tu-2, Pe-8 and La-5 and it's successors.
The location of the oil radiator gives away that it's a Tu-2.
