Hi Scott - generally we take the newest component when dating a watch. We aren't surprised when the difference is a year or two. Four year spread indicates (at least to me) a possible movement replacement. In this example I would suggest dating to 1964. I have a sense that this style case back is an international model as opposed to a Canada/USA (North America) model, I have very little basis, just a thought really.
I do not see any match is our advert dB. Unknown to me.
