1st is a very early (1923 or before)
2nd has an early Snap-on logo
3rd clearly date stamped 1934
4th 1937 – 1948 knurled head style
These 4 S-5 Sliding T bars show a progression from a very early (1923 or before) showing no center grove, a small underlined Snap-on logo and a smaller head.
The first S-5 has a smaller diameter bar.
The next has the same small logo as the first and is dimensionally the same as the 3rd.
The 3rd is clearly date stamped 1934 and has a different logo style.
The last S-5 has the 1937 – 1948 knurled head style.
The first head is shorter – the next 3 are dimensionally the same.
The bottom photos show the back of the heads.
These start with an indentation (alignment dimple?) before 1934 and a through hole (oil port?) After 1934 to 1948
