Man I sure wish I had an A1 desk stand, but here's a B1

As telephones evolved from the candlestick, the next desk stands to appear were of the variety with handsets and in some cases dials. Here is a Western Electric "B Mounting" dial desk stand.  This was Western Electric's more widely manufactured desk stand, which followed the much sought after A1 desk stand.  The B1 here is often referred to as a "102" since they were usually wired for sidetone.
