I have come across the fact that certain transits had 1:132 ratio stadia hairs specifically for easy conversion to chains. In order to make it work one would read a Philadelphia rod calibrated in feet.
A standard 1:100 stadia transit would have also worked if you had a rod calibtated in links and tenths or twentieths. For the work for which stadia were acceptable, tenths should have sufficed.
I have never seen a transit with a 1:132 stadia. Who has used one in the past?
Were any rods calibrated in links?
