I found that if you go down the row tightening the butt plates, any that actually tightened, were cracked. Since it is brass on brass, there is no reason for them to loosen. So if it seems loose, it is actually cracked, and should be changed, even although it appears to tighten, and lessen the 'wobble'.

If you take an old one not yet broken, you might be able to crack it with your fingers. Explaining what this is costing them for the minimum service charge and repair a few and what it would cost them to do it right in the shop. You can do this work at the site quite easily. I'd be prepare them to replace the bridle straps at the same time...
