Have two of these postwar-style Lionel F-3 A Unit Dummy frames. They are die-cast metal, have the steps attached to the rear, and are factory-painted a nice satin black. These were produced around 2000, but will fit all postwar-style F-3 shells (the kind with the metal bracket in the back) from the early 1950's to the present. They have Lionel LLC molded into the underside of the fuel tank.
In the mid-1990's, the tooling for these frames was changed to eliminate the "built-in" headlight socket. Instead, a separate light holder was incorporated that includes both a separate headlight and cab light. 18 volt bulbs are included, so they'll be safe on conventional or command control. The light holder, both bulbs and leads are included with the frame.
Condition is Like New, with just possibly a small nick or scratch from handling that could easily be touched-up with a magic marker.
Price is $25 each plus shipping. PayPal, check or money order accepted.
