Everything looks authentic, at least my 1934 machine has a very similar motor set up, mine has the black bakelite Singer lamp. I have seen older electric models than my 99 and they all have the shiny metal lamp, not the bakelite version (various 1920s machines). Even old 66 treadles often have the metal Singer lamp. According to some sources; by 1921 Singer offered an electrical version of all their models (though model 99 is often listed as Singers first electrical machine, also introduced in 1921, hard to pinpoint anything to a specific year). There were Singer machines fitted with electrical motor well before 1900 though. My 1934 99K is fitted with a B.U.K. II-E., a British made 220V motor. The motor pulley is often bakelite on modles dating closer 1950s and up. A bit more research might give a more precise dating of the motor.
