The design of the neck joint on Gibson solid body EB bass guitars, like most other features and fittings, evolved over time. And a little knowledge of how it changed can be useful in dating these Gibson basses. Basses can have hardware changed or logos and serial numbers lost. The heel is something that generally doesn't get altered in any upgrading or alteration.
The EB-0, EB-3 and EB-4L basses (and their variants) all used the same style joint at the same time. Have a look at some of these joints, and the basses that use them.

1960-1965
1960-1966, as used on all solid-body set-necked basses of this period, EB, EB0 and EB3.

1966-1968
As used on all EB0, EB3 and Melody Maker basses of this period, and some shipped early in 1969.

1969
1969, as used on all set-necked basses of this period, EB0, EB1 and EB3. The large heel offered a little more strength than the previous design. This heel sits flush with the body - there is no 'step' between the two.

This join style is not as common as the earlier 1969 heels; it was used on the three-piece neck EB3s made just before Gibson introduced the slotted headstock EB3. Unlike the previous design, there is a slight step between the heel and the body.

1970-1971
1970-1971. The neck/body join seen primarily on slotted headstock EB basses was similar to the design used in 1969, though with a somewhat smaller neck part of the heel, and a sgnificantly longer body part.

1972-79
1972-1979. As the slotted headstock basses were replaced, the heel size was increased - as used on all set-necked basses of this period, EB0, EB3, EB4L and L9S Ripper. This joint is much the same as the previous version, but typically with a larger heel.
