If I was to supply three serial numbers from three identical 7970 Lightnings, could someone tell me how old they were?
Reason I ask, I purchased two 7970 Lightnings 4 months ago, brand new and then bought a third a couple of months later (second hand).
I want to sell one 7970, the second hand one but can't decifer which one is which!
Any idea how I could tell the age? Do the SN's give away anything?
