This keyboard says Leading Advantage on it. On the back it says VCTL Copyright 1987. Uses as DIN cable and works perfectly. I'm unsure of the type of switch, i've seen it somewhere before though. They feel very similar to PCB mounted blues. I've had a few friends type on it and they liked it.
It is is pretty decent shape, some little stuff but nothing major. I bought this for the keycaps since they are Cherry MX compatible and thick, almost as thick as Cherry Corp doubleshots. They also have a distinctive text which I kinda like.
Price is $25 shipped to the US for the keycaps. I will ship internationally for around $14 (in a priority small flat rate box). If you want the keyboard as well, it is $15 shipped in the US.
