I have seen differences in midyear rubber fastener heads, low on early years with a distinctive flat face and higher on later years with a more curved profile. I will assume M is the same manufacturer on both. I wonder when it changed, or a mix always over the years. We need samples.
If anyone has photos of their originals, please post photos here with the year it came from. Notice the profile differences.
left = 1963, right = 1967

Or.......Is this just a artifact of the tip pulling in on the face, particularly on the doubled up areas?

ps Some repros do not have the M
