I don't have any, but if you need a set then CH Tool and Die/4D Custom Die, 711 N. Sandusky St., Mt. Vernon, OH 43050, 740-397-7214, make them, and list them at $130.54 US..
They also list their own #26 shell holder for 8mm Nambu and I can't find their price for it, but I just happen to have a now obsolete RCBS #25 shell holder made for 8mm. Nambu and if you can find dies, then you are welcome to have it.
They do have a web-site, but they seem to be more old fashioned and even less 'techy' than I am.
Good luck.
