Can This New-York Cds Help Narrow The Date Use Of 1851-57 3c Stamp

I'm petty sure this is a Scott #26. That makes this postmark use curious at least.

Point taken - I guess I'm way off base.
I'll do some looking around for other examples at some point and see....interesting.

Thanks tx.
I'll continue to search for later usage also.

Just to follow up on the New-York single bar (11x3) CDS. It was in use well beyond 1856, into 1861 even.

It's not unusual to see it on a Scott #26, 1857-61.

Per an article I just read from the PF, by Hubert Skinner, there are two non-duplex single bar cancellations from New York from this period.

The one with the slightly larger bar, originates in 1856, while one with a slightly smaller bar originates in 1859.

Postal regulations changed in 1860, to require the CDS to be readable, and be struck on the cover, and not on the stamp. So in 1860 a new duplex cancel, also with an embedded single bar was introduced. It cannot be confused with the prior two.
