Ev - do you know the diameter the 810 shape?

Janice I got this photo from one of those pics with many Crown Lynn shapes on it.  
I can find 809 and I think this is beside it, but mostly cut off.  
Perhaps you have a better shot?
I will add the pic of shapes that I have so you know what I'm talking about for a short time.

I'll have a look soon..
Was this photo at Auckland museum? I think it was one of the first photos that I saw many moons ago. Haha
I have some of those small plates that look like they are from a child's tea set. Wondering if they were used as a butter plate?
I'll add a photo with sizes

The old butter dish is a 457. I will remove the photo now.

What i have are the same of New York or tempo pattern ware. The flat profile. They 12cm in diameter.

Ev. I have the same image as yours.( the one you just showed for a short time)
In the museum hand written shape list it stops at 809 everything prior says flatware.
That's the closest I can get looking for 810 shape/size.
One of the plates above - has the circle made in New Zealand backstamp so these would be prior to Crown Lynn, Ambrico?

Crown Lynn used white clay and Ambrico used a yellow clay.
There does appear to be a crossover time period.
I know the little plate that you mean, but I don't know the number.

I got the pic for the 810 in the gallery from some record, but I haven't found it yet.
