National Lock Brass Floral Drawer Pull with Backplate Single Post Antique Brass

I purchased a bucket of one-off drawer pulls and knobs at an estate sale. The owner was a National Lock salesman. Presumably, they were removed from a salesman display board. Neither the knob nor the backplate is marked National Lock but similar pulls and backplates in the bucket are marked National Lock. There are some pulls that are dated to the early to mid-1970s on the backsides. It is my assumption that these are also of the same period and brand. There are signs of age and "use" as they were stored all together in a bucket. The backplate and knob have minor scratches, nicks, and some patina. The backplate has an approximate 1 7/8" diameter and the single post knob has an approximate 1 5/8" diameter. The projection of the knob is 1" and a little more adding the backplate. It is antique brass color with gold highlights. Please see the photos for a visual description.
