In Poland, we didn't make a lot of bass guitars in the 60s. The Defil factory did make three models introduced prior to 1970, though. The first was the Lotos, a sort of Hagstrom Kent copy. That headstock says it was made in the accordion factory in the town of Bydgoszcz.
Then came the Mambo. I might soon be in the market for one - I'm making a virtual version of its 12-string electric guitar equivalent, and if there's interest in that I'll make a virtual version of the matching bass as well. Maybe the weirdest little feature are the green felt spacers under the pickups. This one's from the 1970s but the model was introduced in 1968.
Finally, the Rytm was introduced in 1969. Gibson ES-ish, with an odd headstock.
