After reading his response to the additional questions regarding the surface cracks, I'd let this puppy go.
He did say he would consider returns if it was an issue. He does have 100% Pos FB, with 90 pieces sold/bought.
If I were interested, I'd low ball it and, if won, I'd send it to Mica and have it restored.
Just my observations on my Alembicless Sunday afternoon.....
