BELCOR Trade Name

I have aquired a tube reciever (Model FAX-52) with the name Belcor on the face. I am guessing it to be from the 60's to 70's in vintage and was imported from Japan to a company calling itself BELCOR OF CANADA, TORONTO, ONTARIO. Would anyone remember this company or better still know who manufactured this product for them in Japan. The tubes appear origional and are all Matsushita. Thanks for any help that can be offered.
