Interesting Drum ... Old Debate

I found an interesting drum on ebay. Its condition stirs an old debate ... but first the drum.
I'm not at all familiar with this type of drum. My attempt at describing or even naming the drum may only misdirect your comments toward my lack of understanding of the history of the instrument and such. So let's skip that ... I am ignorant of the history of the instrument and of the culture of its origin. For whatever it's worth, I spent about half an hour reading stuff online about such drums. There are youtube videos of these drums being played. But yes, I know little of such drums. I've uploaded several pics from the ad. There are several more pics available with the ad. Here is the link:

Here is what can be said ... the thing has an alma. I wonder if it was installed by the original maker or if it was later installed. I see wooden blocks holding it from below. I don't know what opposes the blocks, if anything, to trap the alma. It may just be the angle of the staves ... which are quite angled as you will see.
Let's move on to the debate.
I have a theory: That alma cracked that drum.
That drum would have been better off if allowed to flex a bit ... deform if you will.
But the wood was denied any flexibility ... denied any fluxuations in shape as humidity and temperature varied.
The wood and steel have different thermal expansion properties and such ... and ... CRACK ... another drum cracked by its alma.
Let the debate begin ... or is that continue?
Cheers,
BMac
