I've mentioned this company in a previous post some time back but have recently come across some neat items from them. They are typicaly marked with just a stylized B or like the one nail knob with a B in a diamond shape. This picture is of a heavy duty wire holder marked B on the one side and a U for Universal Clay Products on the other side. The 3X3 spool is just marked with a B.The two smaller @x@ spools(seperated from their unique hardware) are marked with just a B also.
