[Collins] Help on a 637-T2 adjustable dipole antenna

[Jeff Adams]

Hi all,
I picked up a 637T2 today,  and I am trying to figure out how it is 
supposed to work.  Mine is broken, so I will need to repair it.  Each 
of the crank handles have been snapped off.  I will think about 
replacing the green disk that they were attached to underneath the 
frequency dials.  

Mine have two large thumbnuts on top, I assume to tie to the end of 
the wire when you pull the cable out.

But are the two small round thumbnuts holding on the dial pointer 
supposed to lock down?  Mine do not, they just spin around.  

Is each of the aluminium black frequency scales free spinning or are 
they suppose to be attached to the green 
rotating disk/handle assembly?

Any help you can give me would be appreciated.  (Does anyone sell a 
manual for this?  I have not found one on the net yet)

Thanks for your help.
