Will the X30 wide eyepiece for a Kowa TSN660 fit a Kowa TSN1, if so what will be the effective magnification.

Yes, the 30xWide for the Kowa TSN660 series will fit a 77mm TSN1.

Until recently, we have always said the magnification would probably slightly more due to the assumed larger focal length of the bigger scope.

We were wrong - we have finally managed to track down the focal lengths of the TSN660 and TSN1/2/3/4 (a remarkably difficult task!) and they are the same, this means that the magnification of this eyepiece will be the same on both scopes.
