I have been reading the scientific description of RP written by N. B. Tsybulya, a Russian phonetician, for several weeks. In accordance with her opinion, sometimes voiced alveolar approximants in RP can bit a bit retroflex, a bit close to the so-called retroflex approximant. It would appear that I'm mistaken in a way, for I forgot Tsybulya's textbook in my country house, in my dacha, but I'm in Smolensk right now, so I'm very sorry for being quite unable to give you a quote.
