early 20 " Snap on extension with no date markings

[Mark914]

1/2 drive extension. 19 - 20" long I don't see any other markings except the Snap On

can anyone place a year on it ??

This ext. does not show up until the 28 cat. up till then most all the ext. were square shaft. so it has to be 27 or later, just no date code. In about 1930, they changed this to a collar stop.
