I have a yellow 43mm which I could part with, but I actually have 3 other 43mm warming filters (81A? and two 85 pale orange conversion filters I'd throw in for a total of $15 shipped. The conversion filters are "orange" enough that they might work. If they work for you, they might save 1 stop of light loss. One 85 is an Ansco, the other 3 filters are Walz.
