how long ago did sears quit selling beekeeping supplies? i came across some old unused equipment which included foundation. looks like duragilt, with holes on the bottom and without the metal on the edges. i got two boxes of 50 sheets for mediums and deeps. the boxes didn't have a date on them anywhere and the ink was faded from the shipping label. when i opened the boxes it smelled like new foundation and looked exceptional. i've used all the foundation for deeps and the bees accepted it readily. i googled "beekeeping sears roebuck" and the most recent date was 1980 on the search. i guess i am using antique foundation, guess that makes my hives worth more. i was just wanting to know if any of you guys who have been doing this for years would know when they quit selling beek stuff so i could know roughly how old the foundation is.
