This is one of the joysticks that came with the later Amstrad made Spectrums
I found this boxed SJS1 in Revival Games in Plymouth, it's exclusively for the Sinclair Spectrum and was released with the Amstrad built Plus 2 and Plus 3 machines, this is why the lead and plug are grey, as they had different wiring to the Atari standard. However it was possible to rewire or use an adaptor to support those machines
