On non ejector for-ends in the early days before 1912, the "J" spring was the only thing holding the for-end on. Hunter Arms was noticing a lot of complaints about losing for-ends in the field, so they came up with the Curtis style push button release in 1912. This was a very cost related part to make and fit and Hunter Arms realized this and by 1919 they put the banjo style release on Ideal Grades and up without ejectors and left the Field Grade again with just the "J" spring. Hunter Arms, if I am not mistaken said it was a patent infringement because they were not going to say it was very expensive to make which it was.
