The head tube construction is more indicative of a lower than mid range frame. If I'm right, I doubt the tubing is Cr-Mo, and is more likely a 1010 or 1020 carbon steel which would have been par in those days.
You can confirm or disprove my theory about the one piece head tube bu comparing the thickness of the lugs at the top an down tubes vs. against the head tube. Lugs would be the same, roughly 1/16" thickness all over, usually with a pronounced step where they end.
As far as knowing for sure, the only way would be to remove a small sample of the metal and send it to a metalurgist for chemical analysis.
