Types of Royal Ordnance Factories (ROFs)
1. Engineering - This type of factory produced bomb and shell casings and other metal-based components for all types of munitions.
2. Small Arms Ammunition - This type of factory was, in essence, an Engineering factory which specialised in the production of small arms shell casings.
3. Explosive - This type of factory produced the explosives for all types of munitions - cordite etc.
4. Filling - This type of factory took all the component parts and made the finished product. They filled bombs and bullets with the high explosives. The most dangerous of all the types of ROF!
