Post your request in the Classic & Vintage forum, I know there are a couple of riders there who have sought out smaller frames. ANd they definitely understand the aesthetic for the classic styling.

I know one of the moderators, East Hill, rides a smaller frame, I don't recall specifically how small, but she may have some suggestions as well, and she hangs out in that forum.

Oh, and the C&V people will keep their eyes open for you too.

Just do a search for East Hill Alerts...
