Featured Very Old Crown Derby

I have a part teaset including teapot, 6 cups and saucers.

All have the same painted red mark of the crown with D underneath and number 33

Any help identifying the dates for this mark would be appreciated. I am thinking maybe late 1700s to very early 1800s?

Also would you say that 33 is the pattern. A low number indicating an early piece?

Many thanks x

 

I think it's this mark

and 35 as well (on this one)

(shape no., and pattern no.?)

 

Yes, some of the pieces have a 35 in puce.

 

Very pretty !
