How original do you want it? Its most likely a post Bell system refurbishment. It does not carry any Western Electric markings on the housing. The lower housing does carry a refurb shop marking.
It is a 1D2, with either depending on the date, a Western Electric or ATT 32B board. The dial is either Elcotel, or a refurbishment of a WE dial, as that is not a WE hookswitch.
