So I just got this in the mail today... I got lucky. I am in contact with a vintage tech blogger who let me know that someone in Finland had emailed him about converting this for modern-day PC use. Luckily for me, the blogger told this guy it wasn't gonna happen. He then forwarded his info to me, I made an offer and it was excepted - I got a really good deal. Two weeks later I have this beauty.
Unbeknownst to me at the time of purchase, it is NOS. This thing still has the protective plastic on it and he shipped it to me in the original box!! If I would have known he had the original packaging I would have made sure that he double-boxed it. I've also never seen an SE (actually it's FI - same thing) version of this before. It even came with extra caps! The pics he originally sent me were of very poor quality and it appeared as if it had quite a bit of wear and tear. This is certainly not the case - the o-rings on the stems look like they just came out of the factory. Unfortunately during this guy's quest to make it work with PC he had cut part of the cable housing away to reveal the insulation. He did include the piece he cut away thankfully, so maybe it can be somewhat repaired.
I was planning on stripping the switches and replacing them with normal vintage blacks, but now... now I don't know. It sucks because I had plans for these switches and I'm not sure if I have the heart to tear it down. I guess my take on it is this, as long as it's reassembled with the correct era vintage blacks it's ok to take the original switches. There is no way I'm going to convert this for use with a modern PC so I'd argue the switches should be enjoyed rather than sit on a shelf. A lot of vintage collectors will strongly disagree with this though. Opinions? It is pristine. The pics just don't do it justice. Anyway, enough rambling, pardon the cell pics, I'm not a photographer and don't own a nice camera. See below:
From my excitement, I felt the need to document this. I hope you guys enjoy the pics.
