Hi The traditional approach was to seal the unit up at the base. You then baked it out (possibly at 125C) for some period of time (maybe 24 to 48 hours). After that you sealed off the magic hole in the package.
In some cases there was indeed a magic pot under the solder hole that was used to do a final “tweak” on the oven or the EFC set point. I’d bet that there are *some* (but not all) 260’s out there with a teak under the hole. The “no EFC” variant would be a good bet ….
