I managed to get free hive parts that had been stored inthe attic of a 200 year old house for decades. The new house owner thinks they may have been up there for fifty years or so. Everrything seems standard size, but five of the telescoping covers are fitted with thick canvas painted white, rather than having the typical aluminum. This canvas is really thick. Anyone heard of hives covers fitted out like this? The wood of these covers is heavy hardwood. The hive parts were hand made accept the frames, which were the kind that use wires.
