Short Stingray Frame?

[Freqman1]

This frame is a May '67 frame but it seems to measure about an inch shorter (length wise) than my '65 Super Deluxe frame? Were there two different size frames for the Stingrays (not counting Juniors or Midgets)? Thanks, Shawn

It's probably a Typhoon frame,same as a Junior S/R
