I'm not aware of one being sent to russia. If it was I'm sure it was sans supercharger too.
The book "Lavochkin's Piston-Engined Fighters" (Red Star Vol 10) by Yefim Gordon contains the following information on a Russian Lightning;
"Several months before the beginning of the La-11's flight tests GK NII VVS obtained an example of the Lockheed P-38L-1-LO Lightning twin-engined fighter. Its evaluation, which was completed in April 1947, showed that, despite the Lightning's high all-up weight (almost twice that of the La-11), its range with drop tanks was inferior to that of the Soviet fighter. Other performance figures, with the exception of the radius of turn and service ceiling, were also lower."
