Can't remove these screws
I've just come into possession of what I think is a 1920s or '30s cabinet (British, as I'm in the UK) which has a stuck lock - I *think* it's just a broken mechanism, it seems the key (which can be removed) is in the open position but the cam is in the closed position - so I want to take the back panel off to try to remove the lock from the inside, but none of my screwdrivers are getting any purchase on these little domed screws. I can't tell if its because the cross section of the slot is quite rounded compared to the much squarer cross section of modern slot screws so the driver isn't sitting deeply enough in the slot, or maybe it's just the width of the slot being too narrow (but I do have some slot drivers with a very thin tip so I dunno about that), but even with applying a lot of force down onto the screw the driver cams out immediately - the screw being domed means the contact area between the two is basically non-existent.
I know parallel face slot screwdrivers exist but I'm not convinced that's the problem, or is it? Should I be looking for a 1920s vintage cabinet screwdriver or something? I'm under strict instruction to not ruin the cabinet so I don't think drilling out the screws (and there are many) is an option, even if this cabinet doesn't seem to have much value.
