 Is it 3 inches long with a magnifier viewer that comes in a leather holster with a fold over top that attaches to your belt.   Use to have one (wouldn't be surprised if it is still around packed away someplace).

I carried a small yellow Pickett on my belt. See if anyone even knows what that 
is/was.

I was in college, we still used slide rules my freshman year and when one of the 
dormies got a TI 4 function calculator (with LED display) it was like looking 
into the future.  I used IBM punch cards when taking Fortran classes.   PCs came 
out after I had started my first job and used DOS (I still have a Microsoft DOS 
manual).  My boss only bought one PC for the engineering department because the 
price was so high and after watching a sales demo he asked me what I thought of 
the machines.  I told him I could see where everyone in the office should have 
one and he looked at me like I was crazy.
