correcting dyes is very tricky from what my experience has been. oddly enough, i have actually seen "successful" removal of color run with chemicals, only to see it somehow reappear after a few years. I know that sounds weird, but whatever technique they had used on this was actually temporary because the rug was never washed after fixing, but somehow it just was not a permanent fix and came back.
Generally the problem with color run is often if the rug ran once, it will again after another wash or bad spill. "Correcting" color run can be somewhat of an investment and not always successful.
Per age I can't imagine this design would have been made after the mid 60's. Design is early 2nd early 3rd quarter 20th, but rug probably 1950s or 1960s.
I think 1930 would be a bit old for a rug like this only because the areas which would be making a design this adventurous during that time would often be a formal city workshop. However knot density and weave do not indicate a highly refined workshop weaving. It seems a coarser quality. A design coming from a formal workshop would take time to trickle down to smaller city rugs with somewhat less formal workshops as I believe this to be although I could be mistaken. The name mentioned seems to be a blanket for north eastern Iran production. Exactly what it is I cannot say.
for a quick fix on the color run, i hate to suggest this only because i personally do not believe in it, but there are sellers who would chalk this just a bit with ivory oil pastels. Others may give it a tea wash although to make this color fast would take time and a small scale washing plant and often does not come out consistent in used rugs due to varying pile height, color run, stains or possible stain protection treatment. I think the best thing to do would be to sell as is.
