Boeing 737-700 (YV169T)

Sure looks like an old -200.

That’s a 737-2S3(Adv)

The picture is of a 737-100 or -200, not a -700. Look at the thrust reverser on the right engine. See the aerodynamic cover for the outer actuator? That is for a clamshell type reverser, not a cascade-type reverser as installed on CFM-56 engines. Having looked at the other picture available for YV169T, I would say that the fuselage is short enough to be a -100, but it's been so long since I have seen one I can't be sure.

Thank you all for the comments and observations. I just wrote down the plane's registration and the Type was posted by default.

Kind regards
