notes: label: Description
content: This ruled surface has a wooden frame painted black. The frame has two horseshoe-shaped pieces on each of two opposite sides. These have holes which are strung to y-shaped pieces on the top and bottom. The lower surface has red threads, the upper one yellow threads. A pink yarn down the middle is tangent to both ruled surfaces.
label: Description
content: Some American geometric models copied those of European makers. This is one of them. The maker, Richard P. Baker of the University of Iowa, attached a paper label that reads: Scroll of higher order. The model closely resembles a smaller model sold by the German maker Ludwig Brill as a ruled surface with self-intersections forming a line, with four pinch points on the line. For an example of the German model, see 1985.0112.130. For examples of Baker’s model, see MA.304722.30 and MA.211257.123.
