Fellow collector Maurice Tarlo [merci, Maurice!] posted this photo on Facebook. It confirms that Jimi bought this jacket in 1966, as this photo was taken during the first photo session the group did on 16 December that year. With epaulettes!
As for the blonde lady mentioned in my posting of 15 August, former girlfriend of Jimi Kathy Etchingham claims that she is Susan Fowsby, ex-wife of Noel Redding. This is incorrect. The photo is without a doubt from July 1967, and according to Noel's book Are You Experienced? he met her for the first time in December 1968.
