Tom, here are pics of Tod Herrli’s coping plane0AF53FB5-9580-4F9A-9562-C558D8A11DDE.jpg
I have Lee Valley's small plow planes, both of them. They are a delight to use.
Wonder IF those could even use the two sash cutters that the #45 had? One was a mirror image of the other, and you could do both sides, by just swapping out the cutters..
IF one didn't like the profile Stanley made, they could always regrind them to what they did like...
Darrell, an incannel gouge would be useful. I am going to look around for one. It might be time to tune up your stick & rabbet plane1B756BC5-C95C-42AA-9ABE-E9872A893713.jpg

Very good! Now only 19 more copes to make for a 9-lite.
