5 Mark German Reich, war time printing, perforation 25: 17 in the horizontal corner margin pair, right stamp with variety \"right unperforated\", impeccable mint never hinged pair, fresh colours and very well perforated. Manufactured irregularity of the gum, small fissure and minimal tiny stain spots in the margin. According to photo expertize Jaeschke Lantelme BPP (2018) are these minimal restrictions without larger meaning. An exceptional scarce perforation variety!
