While I was passing out my humble pocket door flyer in the "Victorian-rich" neighborhood of Ashmont Hill, a couple said to me, "Our pocket doors work fine, but can you repair the sliding doors on our carriage house?"  That repair became part of my "flagship" website  http://www.fixpocketdoors.com   This  (separate) website chronicles the restoration of sliding doors for Victorian carriage houses (coach houses), small stables and garages.

It appears that radiused tracks for sliding doors was a competitive industry (with the appearance of the automobile).  In the same way - manufacturers had vyed for business in the bustling pocket door market since the 1870s or so.
I suggest that you email me, but if you wish, you can send me a text message (617-792-4676) Texting is the least intrusive way to reach me-if I'm working on doors or fabricating in the shop.          [I don't have mobile email]
