Mat Irvine: This kit was made by Lindberg early on in the development of the aircraft, and is made in a ‘fit the box’ non-conventional scale, as was the style of the time. The original box did state, in standard engineering terminology, ‘Scale 1 inch = 14 feet 4 inches’, hence the 1:172 scale oddity.

Note the scale reference in the original box (above.). Old and new boxes (below) reveals that the latest one has a metric speed conversion added.

Weird scale, but a fascinating kit of a highly advanced supersonic bomber.
The B-70 Valkyrie was designed by North American Aviation as a long-range high-speed bomber in the late 1950s. But the arrival of accurate long-range ballistic missiles meant that the day of the high-altitude strategic bomber was passing. Just two XB-70s were built, with fin numbers 20001 and 20207. First flight was in 1964 and the two craft achieved many records. Fastest speed was just over Mach 3 and one flight maintained this speed for over half an hour.
