Nope, the screws on that trigger guard were put into place, and then, and only then, was the final polish and shaping done, consisting of a sanding and polishing of wood, brass guard and screws, all in place and all sanded together for a perfectly smooth profile - so the fit was perfect. If not perfectly smooth, then not all original or screws moved from one place to another. The photo your posted shows a poor fit of screws to guard.
Now, who can know if those are the original screws or not. But I would suggest, and this is knowledge I've learned over decades, that you should also see what happens when you back off the screw 180 decrees, or tighten it 180s degrees and see how it fits.
This is a One Hundred Fifty Dollar valued bit of advice, meaning that if those screws obviously don't fit well, the value of your rifle-musket is at least One Hundred Fifty Dollars less than if they fit well.
