I've seen a fair number of early Weavers that I thought had some sort of sealer on the threads, or maybe just light grease that had turned hard and appeared to be a sealant.
I have always just sealed the threads with a very small amount of non hardening Loctite, as I have always been afraid that grease might migrate if it got too warm.
