Mills No5 sectioned instructional example

[Aspen]

Hello everyone, I've acquired this interesting example of a 1916 No.5 Mills inert, sectioned, training grenade. Looking at the manufacturer's marks on the base plug this looks to be made 9/16 from the Munitions & Light Casting Ltd, Grimsby. Does anyone know any more about their typical history, their documented use and whether these were made like this at the factory?

Sectioned grenades for instruction were made for use by bombing schools in the UK and in France, and official orders were placed for them. This thread is a good starting point:

They were also made locally in theatre by battalion and brigade bombing staff. The one you show looks to be more one of these than a factory made item.
