Removing a knockout in an older box

[pfps823]

Hi,
DIYer here with I think a super simple question. I'm trying to remove a knockout in an electric box. Tried tapping from both sides with a hammer and screwdriver but no luck. Seems like an older box. Definitely looks more solid than what I see today for sale. Any ideas on how to remove? Photos attached from both sides.
Thanks much!
Peter

Don't think it's knock out Mate, more likely a screwed conduit entry point, see the screwdriver slot in the pic from the outside.

Not sure about the solidity of those fixing screws...even if it was a knockout, and I'm with Pete999 on that, you'd knock it off its fixing if you tried

Looks like it's got a slot in the blank, try big flat screwdriver and unscrew it.
Like Pete says.
If not drill a couple of small holes side by side and hammer a flat screwdiver in and twist.

Can't see any ground wires in that box.

Can' see any knockouts either.

Thanks all. It was just stuck from a few layers of paint. It was a screw mount. Took a while but I got it...

Peter there is nothing to knoc out if you look on the sides of the box you will see 1/2 screw seals just take a screw driver and screw one of them out so you can use that hole
