Interesting!
I wonder whether several case manufacturers buy the lock and latch mechanisms from the same supplier?
As a side note, in the '90s and early '00s, PRS Artist cases came with combination locks and spring latches. They had a red plastic insert to prevent the combination from being set until the owner decided to pull them out and set the combination.
What made me think of this is that the travel case for my BAE 1073 mic preamp came with the same latches, with the same red insert, but the case was absolutely made by PRS' current case manufacturer, not their old one.
Not that I ever lock my cases, I have no need to. Just thought it was interesting. To your point, I'd guess that both companies bought their hardware from the same supplier.
