Picked up an MK1 with a replacement cylinder. But the second cylinder needs the large tube thing to transfer over to it to stay in place. It doesn’t seem to unscrew from the first cylinder, and all dissasembly videos show later mk4-6 Webleys. Here’s another image of a blown up MK1 schematic from an older CGN post, and the tube is attached to the cylinder, making me wonder if that’s how the original cylinders were and there’s no chance of attaching the second.
Please help as I’m at a loss.
