Looking for a little US Postal History help. I picked up a US #2 on cover. It is clear the stamp has been added to the cover later. It is not tied to the cover and based on the cancel I can see on the stamp it end abruptly at the edge of the stamp. Makes for a nice addition to my First Issue collection and I picked it up as a bargain in a trade.
Question is the Middletown, NJ cancel. Any US or NJ postal history folks out there? Is it of the US #2 era? 1847-1851? Middletown (Pointe?) Monmouth County.
Also open to any other comments about the cover that will expand my knowledge base.
