We have a Master Scale Parcel Post Vintage item.   I couldn't find a make year - there are 9 zones with the chart in a circle around the front.  I could not get the arrow to go to 0 and the top scale is tilted to the right slightly (could not get it to straighten).  These are more than likely adjustments.  It does have some light surface rust and wear showing.  This would be a nice piece to recycle.
