Frabjous Times

I'll put this out there in hopes that someone might have the answer for me. In the course of business I came across a problem with some bits of furniture left orphans by manufacturers gone defunct. The two chairs were made by Charles Harland, Inc., which I am informed no longer is in business owing to the demise of its owner. Here is everything I know about these pieces. Anyone who can help is kindly asked to get in touch with me. Thanks in advance.

Update: I never did find an exact match for the mechanism on one of the chairs (the sectional), but happily it turned out that I did not need it after all — it was just a matter of a broken screw holding the mechanism to the frame.
