Found a bit more detail - "Tulio" is just a US importer brand so not really an ID - but as an unbranded bass, it's a Fujigen EB-2. A proper oldie too - this is from a 1965 catalogue for a US importer brand called St George, owned by a New York music shop chain.
Apparently one of the first US importers of Fujigen instruments, when the company was still in its infancy, and operated from an out-building on a cattle farm owned by its founder, Yuichiro Yokouchi.
