Walnut Veneer Sideboard by Honderich Furniture Company

Today, I found this hot sideboard via kijiji Ottawa it's made by Honderich Furniture Company Limited. I paid a great price ($50!) but got noooo info, all I know is that it came from a great mid-century modern house and the makers mark. For sure, it is solid wood - I also found a small chip inside which shows that it is veneer on wood. I think it is walnut veneer - it's big! Via the great Google, I found this info:

In 1911 Messrs. C.R. Honderich and sons, Norman and William and Mr. A. Eydt built a large and commodious furniture factory at the CPR station for the manufacture of cedar chests, kitchen cabinets and bookcases.
Christian Honderich and his planing mill partner, August Eidt, founded the H.E. Furniture Company. The first shipment of kitchen cabinets was made on April 13, 1913. In 1917, the firm added cedar chests to their line. The cedar chest line was decided upon on the same basis as the kitchen cabinets - practically all Canadian demand was being satisfied by US-based manufacturers. In 1926, the H.E. Furniture Company became the Honderich Furniture Company. The company manufactured, at various times, desks, book cases (beautful glass door pieces, "occasional furniture" (coffee tables, end tables, etc), and dining room suites. The furniture was enduringly practical, modest (for the most part) and affordable. There was certainly a pride associated with its manufacture. The furniture was primarily constructed using solid walnut and walnut veneers. In 1967 the factory was sold to Messrs. Dow and Kirkham (Fry & Blackhall, Wingham) who operated it under the Honderich name. In 1969, the plant was sold to Electrohome.
