[Collins] Need picture of bottom of 75A1

[John King]

I need a photo shot of the "closed" bottom of a 75A1 receiver. My manual only shows an "open" picture of the 75A1 in manual photo 5-3 bottom open.
My 75A1 serial number 1881 has the shield box and cover off and I need a photo to assist me in getting the shielding back on the underneath of the chassis before placing the receiver back in the cabinet.
If you have a photo of  "THE COVERED BOTTOM OF A 75A1 OUT OF THE CABINET, I WOULD REALLY APPRECIATE IT IF YOU WOULD SHARE IT WITH ME.
Also, if anyone knows the size and type of thread the screws are that hold the box and shielding to the bottom of the75A1, I will appreciate it if you would share that essential information.
AS a proud accumulator of Collins Radio Equipment, I appreciate your learned assistance.
Thanks and 73, John King K5PGW licensed 60 years
