[Collins] 75S3B parts

[L D Ritta]

Hello All
I have started work again on my 75S-3B receiver, however I lacking some
screws, the one for securing the rack onto the chassis.
I have no idea what size and type they are, they appear to be nonferrous
maybe aluminum. I also lack the L10 bfo coil and a 75S-3B black 
Escutcheon  and the main tuning knob and the af/rf gain knob and Preselector
knob and power  and mode knob.

Can someone explain how the Vfo and the dial and knob fit together, I had a
look at the Collins manuals but there are no pictures showing
These details, I just get the feeling I am missing some component/s, if
someone can point in the right direction.

If you have any of the mentioned parts please holler.

73's Lee.
