thanks for finding and sharing this great video, a snapshot from the past. Yes mate they are certainly WSP depth all round for both the brood boxes and the Supers, go figure they are still a very popular depth hive regardless of those that argue full depth is the only way to go.
WSP depth boxes are still the 2nd most popular depth boxes in Australia, all be it that in some states & territories they are less or more popular for reasons that can never be truly understood. I have always assumed that their popularity stems from those that have hands on experience with them vs. those that have not, simple as that.
Anyway, great find, keep them coming!!
