ID This Helmet....

[rob love]

If I had to guess, I would say Dutch produced in 1956, and the remainder might be a lot or contract number.

IN THE SECOND WORLD WAR, DUTCH TROOPS STATIONED IN THE UNITED KINGDOM RECEIVED BRITISH AND CANADIAN EQUIPMENT, HENCE THIS DUTCH BRODIE HELMET.
THE INNER EDGE OF THE HELMET, AS SEEN PICTURED, IS ALSO MARKED WITH A "VB56 7SLN". THE 'VB' STANDS FOR VERENIGDE BLIKFABRIEKEN ('VerBliFa' - "UNITED TIN FACTORIES").THIS FACTORY PRODUCED HELMETS BOTH BEFORE AND AFTER THE WAR.

Also found this:

This is a Dutch MkII clone. Produced by Verblifa, The Dutch helmet manufacturer. VB 56 stands for manufacturer and year of production. SL etc stands for the steel batch number. The ink stamp indicates acceptence by the ministry of defense. "Goedgekeurd" means approved in Dutch.

These clones were destined for the Dutch Civil Defense and were used until the disbandment of the organisation in the late 80's, when stock was sold off.

The leather neckpiece makes this a helmet for fire brigade use of the CD.

These helmets were never used by the army. The Dutch army used ex-British MkII's and MkIII's till about the mid 50's after which they adopted a variant of the US M1 with the same chinstrap as your MkII clone.
