Regarding the Vulcan B-1 photo. I would prsume that this airplane
was being used as a test bed for testing the engines hung under the
fuslage. Does anyone know what type of engines they were. This is
the first picture of a Vulcan I have seen in this configuation.

Avro Vulcan B1 with underslung Olympus 593 Concorde engine
In June 1966 a complete Olympus 593 engine and variable geometry
exhaust assembly was first run at Melun-Villaroche, Île-de-France,
France. At Bristol, flight tests began using a RAF Vulcan bomber
with the engine attached to its underside. Due to the Vulcan's
aerodynamic limitations the tests were limited to a speed of Mach
0.98 (1,200 km/h). During these tests the 593 achieved 35,190 lbf
(157 kN) thrust, which exceeded the requirements of the engine.[2]
