... I'm with you on this , 20 to 30 hours for a .40/60. sized ARF is the norm.
Maybe if you recover with some iron on covering and don't have any elaborate trim detail.
I just started rebuilding a .60 Revolver, and I know there's going to be a couple of hundred hours in doing a silk and dope finish. Many man days will be spent on just surface prep/sanding. Another 8 hours or so cutting out all the cloth hinges needed and doping them down, another few filling and feathering the cloth hinge edges, etc, etc....and it won't even have any actual covering on it yet.
