Black Jack Cancel Questions

I picked out some stuff from a big accumulaion yesterday including these/



What does the 1st stand for? First mail of the day?



Aby chance this is a brown cancel? (Do you need a zoomed image to be able to say?) edited to add or is it just a faded black cancel? It looks browner to me in real life than on my screen.



The appeal of the black cancel should be obvious, but can anyone make out the red one? I understand retroreceal is no ologer availble. all I can make out is a B and a P. (if thos is a foreign transit cancel, then it may be too hard to figure out).(

This is a little better but doesn't ring a bell with me:

Pretty sure Pkt is packet. Only a wild guess for MB.

I am no expert on black jack postal markings, but in the early 1860s that would definitely be "Hamb Pkt" for Hamburg Packet.

I have several 1857 issue covers with that.

(and a shame its been soaked)

Maybe an earlier similar marking?

yes JB & tex, that's it (HAMB)

I believe "first collection of the day" is more accurate.

Looks like the second stamp (light red cancels) has a double transfer in the lower right corner "cents".

dp - OK, so first in instead of first out

or - here is a closeup of the suspected dt area

Yes it is.
