Your chair (model 140) was made by Bernhard Pedersen and Son. It was designed around 1964. Most of BPS' designs were done in-house, although there is documentation of Johannes Andersen doing some designs for BPS, coincidentally in 1964.
Bernhard's grandson, Thomas, has posted on DA occasionally. He re-started production at BPS in 2015. Here is a link to the contact page from their website if you wanted to inquired further about your chair: http://bpsfurniture.dk/sideboards/contact-us/
