Chicken Tracks

by David Maresco

   Here are two examples of what have been called chicken tracks, for obvious reasons. Trying to determine which precancel overprint it is and how many there are is a difficult task with these, but after careful measurement, viewing with a X10 magnifying glass and comparison with examples of single impressions of  types K, L, M and N, I have taken my best guess.Many of the early bar types can be difficult to identify especially if they are light impressions.
