Thanks, Rob. I expected I was going to have to expand my search parameters. Not that long ago there used to be a huge hardware operation on Wall Street, North of Portage Avenue that stocked pretty much everything one could think of, including BSF items. Went in one day looking for some BGC hardware and scored a great deal on several pounds worth of every size they had in stock. The older chap who served me was delighted to reduce the inventory of stuff to count after no requests for so many years!
