I am considering purchasing a preloved Roulis. The (online) seller has shared that the hardware on the strap is loose (photo below), pulling away from the leather.

Does anyone have experience with this sort of hardware loosening on a Roulis? The other side of the hardware (inside the bag) is hidden beneath leather, so it's not clear to me how the two pieces connect. Is it a screw type attachment? That would be an easy fix that would just require tightening by rotating the strap. If it's something else it would presumably require unstitching and restitching the leather.
I'll happily take it in to H to be fixed, but I'd love a sense of whether this is easily fixable, and what the cost might run, before I purchase.
