Royal Oak? mug with brilliant turquoise glaze +1 other

I think this mug is Royal Oak, but we do not have the shape and have not seen this turquoise glaze before. (The colour in the photo is not quite right.) It was mainly the handle that said RO to me ...


... but this other mug with similar handle is definitely not RO. It has a matt fully glazed base including a reasonably well formed footring, more so than RO let's say.

Later: this is the closest I can get to the true colour

Both these mugs are Royal Oak,see the brochure below.



Another straight mug with wax resist flower.




Index from the pre 1975 glaze book.

Thank you oakpot.

I'm really pleased to see that the turquoise glaze is Royal Oak.
And that I picked the correct name for it!
I will try and get a better coloured photo for the gallery.

I have added a photo of the base of the second mug to explain why I thought that it wasn't Royal Oak.



And here's another one I was wondering about, below.
The glaze is so shiny it has picked up a lot of reflection: it is brown.

That image is of an odd Royal Oak BOAT mug.They were sold as a set of 6 with the name of the customers boat written on each one . See my sample mug below.

Thanks oakpot.

It's wonderful to get all this extra information.
