Hi David ,
My reply was posted while I was watch the rugby on TV so may not have been clear/accurate.
(plus I have to update/edit my album).
The original "War Munitions Volunteer" badge had a red enamel finish , these were issued to workers who had enrolled to work in the munitions industry/factory but had not yet been placed in a position.
When the number of workers required increased it was decided to produce an 'economy' version of the badge without the enamel finish.
They were supposed to be returned and replaced with the 1915 oval version once employment started but many were not .
