Not your average Chamberlain's bottle

Hi,
My dog dug up and old Chamberlain's bottle, However, it doe s not appear to look like ANY of the other Chamberlain's bottles I have seen on the internet. The bottom has: (two separate lines with those words on each line)

BOTTLE MADE
in the USA

no bottle I have seen, says it exactly like that in two lines separated in that order.
Any idea on when it was made or if other bottles like it exist, or what its worth?
Thanks in advance,
Sarah
