I wonder if they use the same tool to position the C350 and C370 poppets for that series' very similar barrel. I saw a video once of René Dupré doing a quick reassembly with something that looked like that.
I ended up building my own by gluing a stub of dowel in a tiny block of wood. If a 370 owner needs the length, I can go measure it. The Tool isn't critical, but helps.
