Three Papa:
I've never seen a split cowl on a 14-19, though as Lynn noted, there are split cowl photos for the 14-19-2 on Russell Williams Vintage Aircraft web site. Here's a worthy one:

I'd look up the owner to see if he has a 337 for the work. You can also order complete records based on N number from the feds. Don't be surprised if there is no paperwork at all, as older Bellancas and Navions lead the league in undocumented mods :wink:
I can well understand your desire for this. Removing those old HC 12x20 props is not a trivial task.
