What I have seen in the old text books is that these resistors all sit in a tub with oil around them. The oil is at some higher temperature..... I have a few of these resistors and no oil in them nor will I be putting oil in them. They seem to work to the limits of resolution of my test gear. 5.5 digit HP meters. Gud enough as they say. I do keep them on absorbent paper because they do leak a bit even after 10 years.
