Canon new F1N focusing screen

[Hadge]

I’m looking for the standard focusing screen for the new Canon F1N. I recently purchased a mint camera and winder from overseas but sadly the screen fitted isn’t the standard one. If anyone has one lying round or knows where I can get one from please let me know. I thought I’d ask here instead of the wanted section as hopefully this post gets more views.
I’ve recently acquired a lovely Tamron SP 80-200 f/2.8 LD BARR MC lens to use on the F1N as this was my combo I used back in the late 80’s and I’m going to get out with again.

I'm not that familiar with Canon screens but have a look here https://www.ffordes.com/search/canon screen

Seen those Nick and sadly I’m after the AE designated version. I’ve got a spot-metered screen fitted so I’m not entirely stuck but it would be better have standard metering with the split prism for focusing instead of a clear one. I have found one at KEH in the States so I’ll see if they can help.
