This is the original model the rest are based off of. Earlier ones say "Floyd Rose" on the base plate, later ones say "Floyd Rose Original". They are the exactly the same. Made in Germany by Schaller, the logo stamp is on the bottom of the base plate. The string spacing on the OFR is .420 inches. We have the parts available for the Original Floyd Rose (OFR) tremolo and some licensed variants. See them below. 

What does Floyd Rose Licensed mean? First some simplified history...

Floyd Rose is not a manufacturer, he is a nice guy named Floyd with the last name of Rose who created a fulcrum style tremolo with fine tuning, then gets the manufacturers to make it in variants while getting a royalty for each one put on a guitar or sold, and then made a fortune doing it... or something like that. Anyway, Schaller of Germany is the main manufacturer and has the honor of making the Floyd Rose Original, along with a few others.

You see, a Floyd Rose tremolo can be made in Germany or it can be made somewhere else. If its made somewhere other than Germany, it's called a licensed model. Even the United States is not exempt (the Kahler USA made Floyd Rose models are licensed). Floyd Rose tremolos are not generally known as "Licensed" if they are made by Schaller Electronics GmbH of Germany, however they technically are. There are many licensed Floyd Rose variants, most are made in Asia. They all look kind of similar, in a general sort of way, but the shape of the plate and the saddles design and complexity tend to be different between models to better distinguish between various guitar lines. In any case, all licensed models are a 2 post fulcrum designs that share the same basic format as the Original Floyd Rose that is made in Germany.
