Anyone know what (track) frame this is?

[MintSauce]

Picked this up last week. I ask because I don't think it's the original name or paintjob. Can't find ANYTHING online.

 

It has some interesting details, like the two seatstays that run into a monostay tube and the seat tube that extends above the toptube.

 

Also, the sizing is interesting....seattube c-c is 51, but c-t is 58 with the toptube being 58 c-c. Seems long and low, maybe intended for pursuit/TT type riding? I dunno....not too clued up, as you might've guessed.

 

It's built with Columbus SLX tubing.

 

Anyway...have a look and tell me what you think.

 

Thanks
