NAAFI Speedy Question

Hi all, I need some advice regarding this watch:

I am selling an Ed White that was delivered to the NAAFI and came to me with box and papers:



Now someone contacted me, saying that the warranty paper cannot been issued to this watch as it's a APAC country code. Well, I know that NAAFI was stationed in Singapore in the 60s and still is in Brunei. So I assumed it was all good with this paper.
Is it possibly the right code? Or had all NAAFI watches been delivered to the UK first? I don't see the reason for that...

Thanks for any help!

This Warranty Booklet was issued way behind 1968, must have travelled back and forth with a DeLorean. But besides that, the Extract is good.

Nice provenance, just lose the guarantee!

Thank you all for the comments!

Thank you, I would like to publish here but I don't have 200 postings, more like 20 😗
