I picked up two T heads at a yard sale last night and wonder how you determine the manufacture date. PK

Look for a little circle near #4 spark plug, if they are before 1923. They are also on some transmission covers right behind the Mag Post.

Here is a sample cast date.

Hi James

One head has that stamp, the other doesn't. Would that be a post 1923? PK
