Back in the 1980s at the peak of the Dallas sidewalk sale K7IRK and myself would see who could get the most BC 221s with a $5 limit. I probably have 8 or 10 left, don't know for sure. All had the original calibration book and worked. There were plenty of other great bargains, a $10 ART 13 comes to mind. Hello Bob. de Pete WA5JCI
