I have one very similar to yours but maybe smaller. Where yours has three of the black metal corner reinforcers, mine has two. Mine is 17" wide x 11.5" deep and 8.5" tall. It also has "24 LBS" above the K&W name.
Unfortunately I can't tell you anything about it. I inherited when my mom died and have no clue where it came from.
I also have a Austin's Biscuit box I got at the same time. See photo. I display them both on top of my refrigerator.

PS: I can't seem to get the photo at a size that this site will accept it. So I gave up.
Email me and I will send you the photo. My email is:
