d'andrea boring head TA220 cat50 automatic very precision and large - smooth

Description

d'andrea boring head TA220 with index pin cat50 with boring tool slide.
Taper in good shape. Boring slide is smooth across range, no tight spots.
It was lightly used and only for special jobs.
The left knob missing but it appears to be a clamp. Additionally,  there is a handle missing from the opposite side of the adjust handle.
This head is very heavy.  Very strong Italian well made and designed.  YouTube videos show their operations.  I confirmed slide moves via rotation.
If you have any other questions or ways I can operate other than how I describe,  please ask and I'll check.  I dont have a machine with cat 50 taper.
This is sold as as. I know main functions work and it's not rusted. I know actions are smooth.
