Estimated age of installation

Could anyone give me a rough idea of when the MEMshield 2 range of boards were introduced? And also, if anyone had an idea of when the old Square D. boards came out. Firstly the ones with the black MCBs & RCBOs, and also when they were replaced by the 3871 QOE MCBs.
Google hasn't been much assistance.
Many thanks
Andy

not sure about the MEM, circa late 80's at a guess. similar age applies to QOE.

Around 25 years old I suspect andy, thats when I was using the MEM Memshield boards a lot, and they were fairly new on the scene at the time and the Big thing back then.

early 80,s for the square d/stablok, you could get a half width stablok breaker as well!
