Unless your action is not original to the stock (which seems unlikely to me) then my original date guesstimate is wrong, and this model 50 stock style was made later than I thought. Always something new to learn!
It seems to me that the available sources are fairly clear about Diana production of the variants of the 35 and 50 until 1962-63, and equally clear about the post-late 60s versions that lasted until the mid-1980s.

Much less clarity about the transitional 1963-69 period between the high-quality 50s-style guns, and the cheapened ones that we associate with the 1970s.
