Not sure when it changed. Dunno why it changed. The date code makes more sense to me than the later month + serial version.

Edit: yes, the weather is miserable. thanks for the reminder.

"4" is for 1974, "I" is for September, so 65swb45 is right on the money, as expected.

Thanks, that makes much better sense. @65swb45 is correct!

I appreciate the help from everyone. Nice to know what I have!
