Help With 1851 Stampless Cvr From Bremen To Ohio

The 27 cent rate is unusual and the "Land Transit" (T T ?) marking can not be found in publications.

There seems to be an erased 42 under the red smudge.

It looks like the cover was carried via Belgium at the 27 cent rate. The "7" is Belgium's debit to the US (the US had to pay 7 cents of the 27 cents collected to Belgium)

That would have been my guess except that the 27 cents rate did not come until 1859. However, going thru Belgium would have explained the Transit Terrestre TT marking from Backnang to Belgium port before departure.

Unfortunately Belgium covers from that period is scarce in US literature. I am still searching for ship crossing & routes etc.

could the date be 1859 with the "9" looking like a "1"

I have several covers from the same source and I will double check. My initial check of ships arrival on Nov 28 1851 didn't match any sailing dates.

The date stamps suggest the entire travelled from Backnang in southwestern Germany 1 November to Bremen in northern Germany on 6 November.

The ST appear a bit too close together to be the 22.5 mm diameter stamp known to be used between 1840 and 1852.
It looks more like the 23 mm diameter stamp known used between 1855 and 1857.

Just a wild guess; could TT be "Thurn und Taxis"

Just assuming the 1 is a 7, the sailing date is 6-11-1857 from Bremen to New Orleans, there are

Thx for all your comments. The date stamp appears to be 23 mm so I am leaning towards 1857. Also there is a smudged 42 that was erased.

I am also looking at Thurn and Taxis marks.
