An element of the hardware ID’d

Went through a 1970’s reprint of John Leighton’s Suggestions On Design, offering just over 100 plates (1000’s of drawings) of motifs he designed.  Came across a match identified as Moorish with the cubic overlapping and interlacing ornamentation terminating with a floral motif.  Many of the Moorish designs also suggested a variation in texture in the background of these illustrations, which would correlate with our Norwalk pattern’s varied texturural and relief elements.
