Brian, et al, I have an old Hallet, Davis & Co. grand with a sectional bent inner rim "cap" - 4 1/8" laminations starting just above the plate, embedding it, going to the top of the case. There are let-in gaps for the hitch pins at the ends of the tenor and bass sections. The laminations are Walnut; in fact, the bentside is Walnut as well (it has a square tail), amazingly sawn to shape from a single piece. The framing appears to be Spruce, I don't know if it is capped with harder material. Cheers, Clark
