"# B-58C: Unbuilt version. Enlarged version with more fuel and 32,500 lb of thrust J58, the same engine used on the Lockheed SR-71. Design studies
were conducted with two and four engine designs, the C model had an estimated top speed approaching Mach 3, a supersonic cruise capability of
approximately Mach 2, and a service ceiling of about 70,000 ft along with the capability of carrying conventional bombs. Convair estimated maximum
range at 5,200 nautical miles. The B-58C was proposed as a lower cost alternative to the North American XB-70. As enemy defenses against high-speed,
high-altitude penetration bombers improved, the value of the B-58C diminished and the program was cancelled in early 1961."
This is what it is, it is a wind tunnel model of the B-58C, which was never built.
