I just picked up this very small frame Maruishi RX-600... 44cm and I'm wondering what the frame is worth.
Tange 1 tubing, has some good paint chips but no dents. Fork I think is Columbus steel due to the faded decals on the fork. I"m going to be selling this frame along with a bunch of parts in the next week or so.
It would be very strange to have a Columbus fork on a Tange #1 frame. Are you sure it's original. I can't get a good look at the embossing on the crown. Regardless, you can check inside the bottom of the forks steering column for Columbus's patented five spiral ridges.
The fame is very rough and very small. The size limits the market and the the new owner would have to factor the price of a repaint into it. Personally, I think there is little value. However, there may be something in the fork, if it turns to be Columbus but it all depends on the length of the steering column. It appears to have a threadless adapter. If this is true and it is a Columbus fork, the value may be virtually nil, as there may be virtually no unbutted steerer length to accept a safe length of quill stem.
The fork had a M stamped in the crown of the fork and had hearts, clubs, diamond, and spades stamped on the inside of the fork. I could barely make our the columbus decals that ran down the front of the forks. I'll take the fork off and measure to see how long a steering tube it has. I'm guessing the fork is not original... but what other fork would have an M stamped on the crown.
... but what other fork would have an M stamped on the crown.
Conceivably, it could be just about any manufacturer with begins with an M. Which narrows it down to about 3 dozen and why you should post a pic of the fork crown embossing. The card symbols on the fork tangs were favoured by many Italian so a Columbus donor fork is possible. Don't forgert to check for the five spiral ridges inside the bottom on the inside of the bottom of the steerer tube (or the Columbus stamp on the outside of the steerer tube).
