Full M900 but with Cook Bros cranks. The bb is a White Ind with a long spindle. Answer bars, Manitou (Bradbury) stem that I had to have the quill replaced to 1 inch. Fork is a Manitou (Bradbury) suspension, a rigid fork would be nice but super rare. Its taken me almost two years to find a stem. The bike came with the modified M900 145mm wide hub and luckily I had held onto a wide (115mm) Manitou front hub.
I'm not sure what tubing is used but its not that crack-tastic stuff used on the later Answer frames. I need to read the old magazine articles I have, I'm sure they specify it. No idea on the weight, sorry.
Fork photo below. I need to replace the elastomers and since I took this photo I've had the steerer replaced with a shorter one:
