1889 - 1891 (approximate. ), interesting lot with 165 pieces of the 50 Pfg value the crown / eagle - issue, all in picky condition and obviously all to the good colour "b" and "ba" belonging and with the corresponding cancellation dates from 1890-91. With also many pairs and suspending gutters. Approve as "ba" calculated already by the Michel-Catalogue over 2000.-, about the half is but the better "b" - colour. To plate flaws not be searched!
