As you all know I do collect contemporary "...wearing..." photographs. And although I do own a lot of custom dagger photographs there is NON with a green striped portepee. On the other hand on postal protection daggers you can notice very well even on fuzzy b&w photographs the red flecking on the cord (and sometimes on the stem). Personally I dare to doubt that these green striped custom portepees ever were produed during the period.
