If this was shot in the 70's in London then it is highly likely it was shot with Cecil strobe, a 5000 magna flash pack and either a fish fryer rectangular soft box with 404 grade perspex or a single C head with a round light diffused with perspex, the background was lit with a 5ft strip light on the floor and pointed up , sometimes with a edge of dog toothing to soften the graduationt,he first shot looks like it was lit with something like a 2Kphotoflood with loads of fill and a flagged back light
