I believe it has to do with the style of the stopper. It seems "Hutchinson" stopper is where it derives its name and is also used to describe the entire bottle.
Applied seals I don't see many of those out my way. That is a real solid find and highly desired - hold on to it, don't sell or trade it. Is it a pontil kick up base?
Got me by the short hairs. The bottle 'appears' to be a flared, rolled lip... hard to tell. It is definitely wonky though. I have two guesses... not American or it's a poorly blown chemical bottle.
Found this on a bank of a creek. The area it was discovered dates back to late 1600's Dutch Settlers. Of course I know it's not from that time frame, most likely Civil War Era. Not rare, but a sweet example.
Found this exploring a bottle dump. It was a glass block coin bank with the back broken off... obviously to get the coins. The embossing is amazing and regardless of its current state, it is certainly a keeper.
I could certainly be a master ink. Not all master inks had pour spouts on the lip. So I'm leaning toward a master ink. As you can see below, no pour spouts.
