Would an Orca in Pochven be worth more or less ISK if sold within it?

Can you manufacture them in Pochven still? I imagen there not worth much more if so.

I recall only Capital Ships cannot be made in Pochven. So presumably yes you can make an Orca in Pochven. Though I would try it with a Porpoise instead if your intent was to use it in that space.
