My 2013 Scott Specialized Catalog has a note detailing the change in numbering. It states:
Quote:
The following items, formerly listed here at Nos. 55-62, are considered to be essays or trial color proofs. They will be found in a separate listing between the Essay section and the Proof section of this catalog. Previous No. 58 has been combined with No. 62B.
It then goes on to suggest that Formerly #60 is currently No. 70TC3e.
Formerly #55 is currently No. 63-E11e
