Thats beautiful but probably weighs too much for my glass back, being cocobolo!

Wow a neck through orion?! Would love if they did that standard, especially with the orion guitars...

It's the same model as my fretless:
 

 
Bass world UK still has the 5 string version in stock.
These seem to have a K (Essence) in the serial number, my fretless has a C and the build sheet says OLB4F Orion
My fretless is 3,955 KG

I thought you had sold that one FC.
I remember trying out an Orion 4 bass about 6 years back and was amazed at how light it was compared to my SC deluxe which has cocobolo lams.
