Where Is Kodalith Fine Line Developer?

I am looking to contact print some of my large format negatives on Kodalith. For this process I would like to use Kodalith "Fine Line" developer. All I see these days is Kodalith Super RT Developer. While this is a fine developer it is not the effect that I am looking for. Does anyone know where I can find the Fine Line developer that I seek?

Bruce: I would try some of the print shops near you, or perhaps the rpinting plant of the newspapers, although most newspapers and prints shops have changed to computer images, you might find a supplier from them.

Regards,
