| The c/n plate on any Learjet can usually be found mounted on the rear fuselage or painted on the fins below the tail. |
|
The earliest Learjet models with small, very noisy engines, and usually only one or two passenger windows. The Learjet was the first "corporate" jet and still looks as good today as it did in the early 1960's when it was first rolled out. |
LEARJET 24
|
A streched LR23 usually with 3 passenger windows (smaller than the 23). The 23,24 and 25 models often have a "nose" at the top of the fin on the front. |
LEARJET 25
| A stretched Learjet 23/24 with 5 passenger windows and engines smaller than those found on the Learjet 35 |
LEARJET 31
|
Winglets are the giveaway for this model. It looks very similar to the Learjet 55/60 but has a narrower fuselage and a single pane cockpit window when viewed from the side. It also has large fins under the tail. It is basically an upgraded LR.35. |
LEARJET 35
| Very similar to the Learjet 25 with 5 passenger windows, but the larger engines are the feature to look for. The military version of the LR.35 is designated the C-21. |
LEARJET 45
|
A very long fuselage version of the Lr.31 with lots of passenger windows and a single pane cockpit window (when viewed from the side) being the identifiers. |
| A "wide-bodied" Lr.31 !!! Look for the small extra side window in the cockpit windshield and the small single fin under the tail. |
| Very similar to the Learjet 55 but the larger engines and the two big under tail "fins" make this model easily recognised. |
