Here is the BAC Bible on Glareshields. Don’t ask how long this one took me.
Here is some official glareshield parts applicability data for the Models 19/23/24/76/77. The reality is that many of the 19/23/24/76 glareshields are interchangeable, with minor changes in things like radio stack vent slots on the top surface.
