57cm Independent Fabrication Crown Jewel SE

What I have is a hand crafted steel road bike. It was built with S&S couplers to allow for the breakdown of the frame for ease of transporting and/or storage. Fantastic ride. I am wanting to get back into mountain biking and willing to trade for a good condition mountain bike. Full suspension would be nice but I actually would prefer a nice hard tail. Let me know what you have.

Here is the breakdown of the bike:
