Nirona Governor Complete or just mainshaft wanted

[flying500]

Does anyone Please have a Governor either complete or just the mainshaft for a Nirona Tin bodied Nirona?
It is for the Rectangular rather than the Triangular motor if there is a Difference.
The rest of the machine is so nice that I want to complete it.
Also does anyone have a copy of the Nirona label that sits behind the Diaphragm on the soundbox and any Technical info on these lovely little machines?
All the Best
Jerry
