This ESLA catalogue features a broad description of the ever-popular Bi-Multi range, detailing a mind-boggling
number and variety of angles and types. It seems that a Bi-Multi lantern could be specified for almost any road condition.
The rest of the catalogue comprises of a rather incomplete list of brackets, columns and other lanterns. From the gaps in the numbering schemes, it
becomes apparent that ESLA produced a far wider range than previously thought.
Since the reclassication of sodium lamps by ELMA is mentioned (and dated as the 15th November 1938), the publication of the
Final MOT Report (and the specification of the Group "AL" lantern), and the note that the firm produced their
first scientific refelctor fifteen years previously, then this catalogue dates from 1938.
