Do you think then that the derailer that was on this bike is actually the incorrect fit?

problem is of I do this, the derailer is upside down?

You're not making this easy by posting on two threads!!
Turn 180. Face claw same way as dropout. Edit: deleted. Image of back side of claw?
Edit: from other thread:

So the nut for that bolt slots into the 'back' of the dropout.

OP says it was easy to get off so I assume it came off the same bike....

If I do that then the position is incorrect, I've already shown this. I have read the post he gave me however I'm trying to understand if the part is simply not designed for my bike

"Turn 180 degrees. Face claw same way" as dropout so that the open end of the claw faces the same way as the open end of the dropout.

You’ve got it arse about, just turn it.

 

[rorytymon]

Exactly. Feed the little nut into the dropout first. The open mouth of the claw lines up with the open mouth of the dropout. The flat sided nut sits inside the dropout, preventing it from turning and you tighten up the bolt so the thing sits snug and the claw and the dropout are lined up to receive the wheel.

It will look like this. https://www.cyclechat.net/threads/help-with-vintage-derailer.263587/#post-6047626

Or here's an amusingly dirty example

Doesn't fit though

Think there is a lesson here for all of us. Before and during any dismantling and rebuild project, take lots of photos to help the rebuild.

It will fit, you've just got it in the wrong way around, take the wheel out first, its also much easier if the bike isn't upside down.

It goes in like this.

does bit number 8 fit in the back of the inside of the dropout with the wheel out ?

 

[Gunk]

I get the feeling that he is missing number 8. you can fit it without the lock nut.

See OP's image I copied across from other thread: it's there.

What everyone else has said, put your bike the correct way up. The little metal tab bolted to the derailleur goes in first so that the dropout on the derailleur & frame face the same way.
this will make the dropout shorter so you have to align the wheel carefully when refitting it

It will, trust us
