You might want to take a look at this website. It is a "pictoral evolution" of the FED 3 and the various lenses incorporated in each stage of production.

The following is a quote from the "Camerapedia Website", which may help explain what the L/D designation is all about.
"The Industar 61 L/D is possibly the most highly regarded lens for Ukrainian Leica copies. In an L/D or L/Z version of this lens, the L indicates that the lens has Lanthanum in it, and D indicates M39 mount while Z indicates M42 mount."
By the way, you will enjoy your FED 3.... Have fun!
