For parts 

Used Honeywell direct coupled actuator

Not working but as parts are hard to get presently (and expensive), it’s possible that someone may be able to use parts from this to repair their own actuator or make this actuator work. I am not technically minded and simply had a technician replace my actuators (2) as I was unaware whether they are repairable.  

Welcome to make an offer and pick up free  - I have 2 so if you would like 2, just double the price.
