What is the name of the type of latch/bolt system where a twist handle retracts vertical rods?

Question

I have an old LDV 400 Convoy which has double doors in the back. There are latched using this vertical rod system, which I have seen before, but can't find out the name of! Just to clarify, you twist the handle on the outside, this retracts the two vertical rods from their latch housings at the top and bottom of the door. Does this type of system have a specific name, and does anyone know where I can get a replacement/spare parts from? Thank you!
