Where can i buy a pea variety called 'peashooter'?

[kippers garden]

I love this variety of pea and i can no longer find it to buy on the internet.  Does anyone know where i can buy it from.  It's called 'peashooter'.  It is a tall growing pea but the pods are long and full of lovely sweet peas and there are loads of pods.
