2 Witticomb and 1 Tobey

I inherited some furniture in need of help with the seats. I'd like to learn more about the pieces to select a correct fabric that honors the piece and fits with its time frame/history. I've included photos.

I have a chair and bench that are both labeled Witticomb and both have 1978 engraved on the pieces.

I have a Tobey chair with 3951 8 1922 engraved on the piece.

I haven't been able to find much about any of the pieces, so any information would be very much appreciated -- dates, original pricing, current value estimate, etc. I do not plan to sell these.
