For what it's worth, The Asahi Pentax Guide (Oosten) says:
"The lens can be distinguished from its successor (Model II) by a small glass
protrusion on the rear element and by its slightly
greater weight."
I think this would require a side-by-side comparison. Elsewhere, the same source says:
"Super Takumar 1:1.4 / 50mm
[Model 1]
Year of Mfg: 1964 - 1965
Elements/Groups: 8/7
Diaphragm: fully auto
Angle of View: 46 deg.
Minimum Aperture: 16
Minimum Focus: 0.45m
Filter Size: 49mm
Length: 37.5 mm
Largest diameter: 59mm
Weight: approx. 245 grams
Product number: 358; 35800 (from 10 - '66)
Number Produced: n/a
Serial Number Range: n/a
Changes include: diaphragm ring with fine or coarse knurls; round or oval lettering."
"[Model II]"
(only differences listed)
"Year of Mfg: 1965 - 1971
Elements/Groups: 7/6
Weight: approx. 230 grams.
Product Number: 378; 37800 (from 10 - '66);
37801 (white dot f/2, from 11 - '66)
37802 (from 4 - '69)
Changes include: A/M lever, Auto/Man lever, small internal mechanical changes and
white dot f/2."
The only things (without taking it apart) that will set them apart for sure are:
The product number on the back of the Auto/Man switch, and the weight. The
"protrusion of rear glass" would be easier to assess
with both types of lenses to hand.
