Whenever I see a photo of a literature cart, they all look the same to me. Are they a standard design? Who makes them? Does the WT sell them? If they do, do they sell them to Kingdom Halls or individuals? Are they different in different countries? Are they just bought off the rack at hardware or office supplies places?
It may seem a bit of a trivial thing to be asking about, but getting a cut from something that JWs are required to have has been the WT's modus operandi in other areas. Something needs to be purchased for use by many JWs around the world for their kingdom service. Does the WT get a piece of the action?
