Which link? The microscope or the stand? I haven't a clue when the mic stand was acquired. When you get old and move house a couple times you tend to accumulate a few "lifes" worth of stuff.
The microscope is on amazon. Plugable USB Microscope, I initially got it thinking the flexible arm/stand would be long enough. However, the clip that connects the scope unit to the arm is removeable and has a standard 1/4" photography thread mount so you could use a camera tripod as well.
It used to be $25-30 but it's up to $45 now. I do think it's a good value and my first one had a dead pixel right in the center. I contacted the company and they sent out a replacement almost immediately. I donated the other.
