I can't date either one for you but you can date the F yourself. Look at the section of the frame that the lever hinges at, also know as the lever boss. You should see a stamp with a letter/number inside of a circle. This is the lever boss code(LBC). Started in 1949 which is shown as "A", 1950 = B, 1951= C, etc. You may need a magnifying glass to see this clearly. Your F should have been made in 1955 or later but no later than 1959.
The 29A can be dated if you want to get a factory letter from the Historian. See the sticky above for contact info.
