Dear MMD's: I am looking for slotted round head wood screws that are
_not_ bright zinc coated.  Most of my sources (like McMaster Carr,
MSC, etc.) have round head wood screws, but they are always bright zinc
coated.  The originals in the orchestrions were always black.

I would like to keep the original look when I do a restoration.  Can
anyone offer a source with a comprehensive availability of sizes and
lengths?  Thanks very much.
