I Always suspected that "Shaftsbury" and "Eros" guitars came out of the same factory as Eko's, the construction methods were too similar to be a coincidence.
EKO also did a nice Acoustic Bass guitar with an oval sound hole. The body is about the same size as a Ranger, but tapers to 135mm at the tailstock (trapeze type). The neck appears to have frets but is in fact fretless, the frets being inlaid flush. The tone is a bit thin, but it does make a good practice guitar.
