Nice one, Anik!
Unusual colourway, and fairly sophisticated splodgy, I'd reckon it's probably early '70s, possibly "post-Harris, but before Said took over in '75, while Eric Dobson was in charge", at a guess.
I tend to put the "yellow and orange together splodgy" in a different class to other later splodgy stuff which uses far simpler colour combinations - yellow and orange are both notoriously difficult colours to work.
I have no confirmation that the yellow/orange combination is Dobson period, it is pure speculation and observation and my own judging of the quality of the pieces from the different periods.
It's a lovely shape too, I like the bulgy bottom.
