Hello! New and first time posting. Glad to find this resource. I am a river bottle hunter, and usually find things from the 30's forward. Yesterday, however, i found what i think to be very old bottle. It is brown, no vertical seams, looks as though it were spun in a mold. It has a blob top style applied top with a seam (pics). The base has only a small "nipple" in the center. No markings whatsoever. I think its the oldest ive found but would love any input i can get! Thanks for your time.
