Northern Telecom SP-1, SG-1, Does anyone have photos of this system?

Another history question.

So I've been reading a lot about the SP-1 switches from Nortel pre SL-1 days and I am curious if anyone has any photos or information on these switches and what the phones, equipment or switchboard looked like?

I remember the ghastly grey/green colour of the SE and the SG and the canvas zippered wire harnesses. Same colour metal and textured finish as old NE 1A2 shoeboxes. They looked dead but could still roast diodes. This link has some starting information.
