If you have a small screw Allen wrench that will fit in the back where the spine of the blade sits that might help tighten it up. Stick that in there then firmly press the head down on a hard surface and rock it towards the comb to close it up some. When you pull the Allen wrench it should hold the blade more firmly.
.....They can be springy I know...You have to make sure its pressed down more towards the side/angle where the blade will be exposed ..If you cant get it to tighten You could use a thin shim on the top side of the blade to take up the gap...I have never done this but it should do the job... Billy..
Here is what i do. I get a small drill bit just large enough to open the spring slightly the drill goes to the back of the spring. Then slide a small allen wrench in to open the blade slightly more. Then gently massage the front of the blade to bend it down slightly.
I just received Bunny Kelman's C1 (C222) It is in need of some cleaning. It cycles blades fine. This looks to be a well used razor. But everything functions fine. I will be cleaning this up today. It will get its first test run tomorrow as I shaved last night with my PAL injecto-matic, and I will not have enough stubble to try Bunny out properly. So that will be my Sunday morning shave.

Have Bunny all cleaned up. HE turned out better than I expected. A good scrubbing with Scrubbing Bubbles pipe cleaners and a toothbrush. I got a bunch of gunk out. I will be using this tomorrow. Bunny
