used The extensive and very valuable study of plates 12 to 177, the strength contained in the earlier plates with 12 (113), 13 (3), 14 (14), 15 (22), 16 (59), 17 (90), 18 (122), 19 (25), 20 (34), 21 (49), 22 (24), 23 (25), 24 (21), 25 (50), 26 (20), 27 (51), 28 (40), 29 (28), 30 (61), 31 (33), 32 (35), 33 (30), 34 (67), 35 (15), 36 (24), 37 (16), 38 (37), 39 (16), 40 (21), etc. and good representative groups of later plates; the earlier plates with many matched pairs or trios illustrating the differing states including 40 KB re-entry, states 1, 2, 3a, 3b and 4 (the last being on entire), later with 176 and 177 imperf. examples with R.P.S. Certificates (1987), many varieties noted with re-entries, watermark inverted, etc., a number of multiples with pairs and strips, cancellations with a good number of distinctive Maltese Crosses, a few struck in blue, numbers in Maltese Cross, etc., the adhesives mostly four-margined and generally good to fine. A superb basis for continuation. (many hundreds)
