Great collector's piece!

The pictures give a fair representation of condition.
excellent condition! in immaculate condition for i'ts age.

As an example, a vintage 1/10 12 K G F indicates a frame with gold content of about 5% pure gold when you exclude the plastic parts, lenses, and screws. To be more exact, the frames are 5% pure gold, 2.5% copper for wear resistance to the gold finish, 2.5% silver to retain the yellow color of pure gold, and the balance magnetic steel in the core. The "G F" hallmark does in fact mean "Gold Filled," but when you consider the relatively small percentage of gold the frames contain and the fact that the gold is on the surface of the frame rather than the core you can see that the G F marking is somewhat a misnomer. It should also be noted that the "G F" mark is equivalent to the "G.O." (Gold Overlay) mark and the "R G P" (Rolled Gold Plate) mark all used at different periods. Each of these marks implies a gold content of at least 5% by weight. In this type of plating, a layer of gold is attached to the core metal by a combination of pressure, heat, and chemicals. This is the origin of the "Rolled" in R G P, i.e. the gold is literally rolled or pressed onto the core metal. This method differs from electroplating in that the gold content in electroplating is less than 1% by weight. The idea behind R G P is to put enough gold on the core metal such that there will be no wear through at least 30 years of wear. Obviously the process is better than expected as we've never seen a vintage B&L Ray-Ban gold filled frame with wear through to the finish. The bottom line is that a G F finish will last indefinitely with no significant wear to the gold plating at all. Remember that a 12 K gold alloy of 50% gold, 25% copper and 25% silver has a hardness rating of 160. That's pretty hard compared to pure gold which has a hardness rating of just 20.
