2 Questions: P-38L Rear Radar/"Phantom P-38"

Couple questions on P-38 lo

Came across a reference to installation of a tail radar
on the P-38L from http://p-38online.com/p38l.html.

One interesting improvement was the installation of a new
tail-warning radar system. It would signal the pilot through
flashing lights and bell sounds when an aircraft was in
close proximity behind the aircraft.

First I've heard of this for any operational model fighter
aircraft of WWII.

Was this an actual feature for the L model or an "option"
or just planning that never came to fruition?

Also a question regarding the so called "Phantom P-38" of
the Italian campaign (http://p-38online.com/phantom.html).

This is the story of a P-38 captured by the Italians and
used against bomber stragglers. I've heard it before and
believe it to be true, but this page provides a lot of
detail on the subject I've never encountered before.

The story describes the efforts of a bomber pilot shot
down by the Italian and his efforts at vengeance. This is
a story fit for Hollywood!

I liked the part about Lt Fisher, the bomber pilot visiting
the wife of Rossi, the Italian P-38 driver, and using the
visit as a means of infuriating Rossi into an attack.

Lt Fisher allegedly died in a crash during the Berlin
Airlift, and Rossi was a mourner at the funeral!

Anyone know if it's actually true, or more simple fact
that has been greatly embellished?

If you're a P-38 fan, this is a rather nice site.
