This bass looks to me to be a similar or identical model. Well it did, before I restored it!
It needed quite a bit of work including a belly patch and neck spline graft to reduce the huge string length. But it has ended up a great bass, for a ply bass! I feel that it probably dates from the '60s, going on the style of the label more than anything else ...
