No problem, thanks for the photos.
It's not one of the 'Australian' fakes that we've seen.
Lots of positives in my opinion - case looks great, crowns seem to be the correct UG versions, correct narrow font on the bezel and you even have the correct brick link bracelet ( 22mm 'U' end links?).
Aside from the obvious fact that it's missing the Polerouter Sub text, my only concern would be that your lume, both on the dial and in the hands, looks very fresh and tidy for a watch that is almost 60 years old.
It would be interesting to see the movement and the inside of the case back.
Are the case reference and serial numbers present on the outside of the case back?
