Window and door detail parts?

I am new to this 1:48 thing. Well, I did some 1:48 modeling, also known as 1/4" to a foot modeling, in architecture school, but it was not specifically of the railroad variety.

I am curious as to what is out there for window and door detail parts. I am looking for some windows for various On30 kitbash projects. I have run some Google searches and I know how to do that, but it doesn't really tell me what O-scalers like to use for wooden door and wood-sash windows. For time period we're looking at 1920s-1930s.

Thanks in advance for your help,
Adam
