The Camp minnow trap is probably the most widely available and recognized glass trap around. It was designed and patented by Carl Camp in the early 1950's. Although they say "Checotah, Oklahoma" on the trap, they were not made there. The traps with all the writing on one panel were made in Sallisaw and Cedar Oklahoma, and the later version, with the writing split up on two separate panels were made in Mansfield, Arkansas by the Johnson Glass Company. They were made until sometime in the 1960's. There is another trap which just has the words "one gallon" on it, probably an early version. The triangle traps (bottom of the list) were made from the mold for the Acme trap, but shortened by about 2". They were probably made in the mid to late '50s.
