Sweet. Now you are ready for spring. What do the mystery boards look like?
The boards on the right are actually used in a special hive box to hold the section comb honey square boxes.http://www.draperbee.com/beesupplies/SectionComb.pdfthese are the boxes used in this hive box.http://www.draperbee.com/beesupplies/supply%20images/woodsections.jpgI would think some of the real shallow boxes in the left side of your first photo may be the boxes that held these comb sections.
Are you planning on disinfecting the supplies ? If so, how ?
Lucky you!!! What a great find! Woodenware is a bit pricey but I haven't been able to find any used (or nearly new) equipment here where I live. Keep pestering my husband to make me some...
