ZWO EWF EOS II

The black attachment that screws on to the ZWO Canon bayonet adapter on the right steps down to M48. Does anyone know whether there is an equivalent part which steps down to M42? If there is, this attachment should achieve 44mm back space enabling a ZWO camera to be used with a Samyang 135 and a filter wheel.
