Had this thing around for a while now....no idea what it is for. It is Air Ministry marked, and apparently for a .50 gun of some kind. I've poured through online schematics and come up empty. It is 1/4 inch steel - 18cm long, and 5.5cm wide.


That's clearly the Spring Guide Transporter.It transports the spring guide. To where and how, I have no idea.
