I, too, am looking for information on a Whittall Anglo-Persian rug. The numbers on the back of the rug are:
100 35 4, and the next line is 1 38.
The rug is about 9x12, the background is dark steely blue, and the pattern looks like it was inspired by a Chinese moongate. The colors in the pattern are rust, acid green, two shades of antique gold, and a lighter grayish blue. I am guessing that the colors would be incredible with Mission-style oak.
My neighbors gave me this rug back in the mid-1980's -- they were in their late '90's. They told me they bought the rug specifically for their bedroom. Now, whether this meant for their first apartment when they married (probably just after WWI) or when they moved into this building which went up in 1941 (their retirement home), I don't know.
Thank you so much for any information you can give me about this pattern.
