Hi Brian - looking at the photo, I'm not sure what you mean here about the frame looking different...
The dark frame has not a spec of wax or propolise on the sides of the top bar yet the comb is wider then the bar.
No Lang colony under my control does either of those things.
I run 9/10 in all brood chambers, so a little fat in the comb is a good thing
amongst brood, not a point of contention at all
My bees will build comb or support structure up on the sides of the top and bottom bars. They may even build burr comb on top of the top bar contradicting the idea that bees cannot build from the bottom up.
Clearly you struggle with more than language use. : grins:
In my third year of beekeeping I got to help a commercial beekeeper extract honey. That gave me an opportunity to see what supers look like that have been used a number of years.
The frame you cite - and a number of others in that box - predate my Agri.School days, the very place the theory was put upon us in fear of bad grades.. heh
Some were so used the frames fell apart before they could be put in the extractor.
I won't critique your "commercial beekeeper" in h/is/er operations competency if you leave my carpentry competency well bee.. heh
I didn't see any boxes that had the appearance shown in that photo. So when I saw similar things in the commercial's boxes that I see in my own it was of no concern to me.
What you see or claim to have seen has already been put to bed as
poor vision, evidence quoted - your poor attempt at coverage noted.
"because they will propolise it shut"-- what sheer nonsense! : smirks:
I am sure my treatise on airpaths will truly have you in coniptions when published... heh
Here is one of my brood frames:

see the cells built up on the wood?
I see a lot I would tellya how to fix... if you were a genuine beekeeper.
Michael Bush is a beekeeper, the real thing. But that is the end of it, there exist hundreds of thousands of like skilled personas around this planet. Some possibly way more philanthropic then he?
I'd wager that should you ask him he did meet a few whilst "Down Under", like
Compliments.
