I bought this either in 1986 or 1987. I don't know the model number or its composition. I tried to research this was unable to find the exact model. I did find similar looking models which I based the asking price. 

This is new and I have never used these pens but I have taken them out many times to admire the set. It comes in its original velvet case. Surprisingly the ink cartridge in the ink pen still works when I tested it. Its blue medium.
