From the bit of research I did prior to my trip to picking up the bike I knew the Turbo did not come stocked with an all chrome fork. So when I got to the seller and saw the bike I knew I had to ask about it. In most cases forks are replaced obviously because of an accident. I asked about it but he assured me it was never crashed. He explained that in the mid 80s he wanted the entire bike to be upgraded to Dura Ace components, including the headset. But the bearings in the DA headset were bigger than the bearings in the Suntour headset. This made the OEM fork too short to make it work, so he had it replaced with another fork. Honestly, I have never heard anything like this.

I asked if he still had the original fork but he did not. The drop-outs are stamped Shimano, not Suntour. And yes, it's lugged. I guess I will have to pull it all apart to see if I can find a stamp. I'm not familiar with the Tange Prestige fork. Does it include 3 circles on the inside lugs? That's what I'm seeing. I'll post pictures later.

Btw - Robbie, I'm honored I got your attention...
