I like them whether they are forged cancels / bisects or no.
The New Brunswick originating cancel of Saint John N.B. (ST.JOHN N.B.) is correct for the period as Saint John was the major shipping port in the Maritimes at the time. Halifax was just a military port and not much for shipping lumber (the main cargo) or people at the time.
Saint John, NB, (as apposed to St John's, Nfld), was also, in time, the terminus of the Intercolonial railway (after the Canadian Pacific Railway) from Upper Canada. The railway did not reach to Halifax until later.
Halidax was a port in use of course, because of it's deep harbour (matching New York), but Saint John was in the right place at the right time.
According to the Nova Scotia Stamp Club president there is a fellow who collects NS belonging to the club. I could perhaps send a note through the web to see if he might respond.
Or, you could contact NS stamps web site email. I think that worked before with one member here.
