Identifican request - 3 Valve mains superhet

[Sparks]

Here are the fixing methods of the IF cans, as you will see, they are clamped under lugs that are part of the main chassis.   They could only be removed by brute force, and then would probably be impossible to get back in again.      The tray shows what I have taken out or replaced so far.   It really was in an awful mess!
