First very many thanks to JP and Mudturkle.
One thing I forgot to add is that this so called "Thai Banana" is rounded and smooth. I.e. It’s not angular in cross section.
We have a market here in the mountains and I sometimes see these fruit however they are in popular demand and sell out quickly. I plan to take a photo and post it as soon as I can find it again. They have a creamy slightly ascerbic apple flavor.
I looked at the link posted and the closest picture I could come up with is shown at the link below.

Just a note for those interested I am building an Asian compound as part living and part Buddhist retreat on 1.5acres. I am trying to make this area as self-sufficient as I can. There are so many things that grow well in the tropics however Banana's are an obvious choice. We can cook them ....so many Asian style dishes, make custard and fruit smoothies…. Etc. etc. etc. It is very difficult getting non-native plants imported here in R. de Panama however the Aduana usually turns a blind eye towards a few seeds.
Thanks again: Bassa
