.455 webley cylinder headspace rings

[Soundguy]

As you know, many .455 webley had their cylinders shaved for 45acp and moon clips.
A few years ago there was a fellow selling headspace rings on eBay and other places. The ring alloys use of regular 455 ammo.. Basically it's a spacer.

I bought one many moons ago. Went looking for another now that I am getting a second .455.

Can't find the seller. Anyone know of a source?

Thanks

The caveat here is I have no idea how well it worked, but I know of at least an attempt being made to insert the .455 rounds into black rubber/neoprene plumber's o-rings of appropriate size. If the right rings were selected, I can't see why it WOULDN'T work.

All I know is the spacer is 048 in which for stainless steel is considered 18 gauge and it works perfectly as a head spacer unfortunately easy materials to drill like Copper Brass and aluminum if you look at 18 gauge material on them they're more like 04 and that's not quite enough that 048 makes a difference
