I was thinking a very late 69, but privious owner claims ps and 44 were in there since it was new....and I know better. ;D the 44 does have drums, but not sure about what ps box is in it.. I just ordered a marti report and had it rushed so I should know later today!
If they were the original owner, then it's still possible that the PO was correct and it was a factory 44. Not a regular one like we're used to seeing after '71.5 Broncos, but the one I call the "hybrid" which is a 44 center section and the same outers as a 30.
So this would have the 44 front cover, but smaller axle tubes and instead of ball-joints would still have king-pin bearings.
There were a very few of these installed on EB's between '68 and '70, with most of the ones I've seen on '70 model year Broncos.
Nobody has really come up with a good explanation of why they were there, but we've had some pretty good discussions over the years about it, with some good, logical and plausible reasons put forth.
Be interested to see if yours is one of these, or a later ball-joint version.
