M1 safety with the tip broken off?

Now, here's a question. I have seen M1's with the safety having the tip broken off (to allow the safety to engage with the hammer cocked or no).
Was this a field modification?

On another sight members chimed in with having seen this on Greek and Danish returned rifles.
Was this a field modification or just reusing a damaged part?

I think it's just broken. Wouldn't pass USGI inspection, but who knows about the Greek maintenance program?

Yep, that's just busted.

So it would appear that it is just a fairly common break during foreign service?

That was what would go wrong with the safety. Then you replace it.
