Architectural Drawings for any old brownstone or tenement exterior

I have a project that involves creating an exact scale model of an old prewar NYC brownstone, townhouse, and tenement—preferably those that seem ‘typical’ of their building type. I haven’t been able to track down any web resources.

I am aware that the Buildings Dept has drawings, and I took a day out visiting them, but every plan that I found was illegible due to the fact that the microfilm was of a pencil drawing that at the point of photographing was probably at least 60 years old. Some were also missing the exteriors, which is what I needed.

I spent some time in the Columbia U architecture library, but the books only highlighted the mansion-type homes of the very wealthy, or those by famous architects—not the typical brownstone or tenement that is most recognizable as a classic feature of NYC neighborhoods.

I would greatly appreciate one or the other pieces of help:

1) An architectural drawing of a building that you have in your posession. I’ll pay a modest price for the hassle, and I’ll pick it up.

or:

2) If you can point to me a resource—such as a specific book title, or specific place in the Municipal Archives, the NY Historical Society, etc, where I can find what I’m looking for.

ALSO: designs for lintels, cornices, stoops, railings, etc, will be something that I’ll need too for the project. Anyone know how to locate designs for any of these?????

Many thanks
