Something suddenly sticks out. Einstein DID know the Lorentz 1904 paper after all. The reason is notation.
Up until at least 1900, Lorentz used the letter "γ" to represent the transformation factor, following Voldemar Voigt (1887), the first researcher to consider transformations involving functions of v/c. During the early 1900s, Lorentz was publishing work about electron theory and, specifically,calculating the electron mass. In this research, he was running against the theory of Max Abraham, and the letter "β" was used to represent v/c there. I doubt Lorentz would have reused "β" to also represent the transformation factor in his electrodynamics at that time. It is (apparently) not until the Lorentz 1904 paper that "β" suddenly started getting used (don't know why) for the transformation factor, rather than "γ". Einstein used "β" the same way in his first relativity paper (1905). That is a big coincidence, if Einstein didn't know Lorentz's 1904 paper.
Miller {AESTOR,Addison-Wesley(1981)} states (section 1.15.1) that Einstein "maybe" knew this paper of Lorentz.
