you might have some luck with a seed savers membership. Collectively the community there has a ton of varieties. Although the membership itself is slightly pricey, so it might not be worth it to you.

I have grown the Golden Cushaw, but it has since disappeared from the market. Actually it is a C. moschata (butternut type) that is shaped somewhat like a cushaw.

Thanks everyone. I emailed Sand Hill preservation, and they said that the picture I had was likely of a squash called Piena di Napoli, it's a squash from Italy.

try orange cushaw from baker creek
