Unknown shell holders

[Herb]

I just got three shell holders with H5, H6, and H8 stamped on them. The H5 appears to fit my .41 magnum, however the other two don't seem to fit anything I have handy. Any idea on who made them and what do they fit? Thanks in advance.

Reg, the shell holders look and fit like regular RCBS. Sorry no pics, just trying to find who made them and cross reference them.
Thank you, Herb

Thanks 44Vaquero, just did a cross reference, no wonder they don't fit anything I have

Herb, if they are older ones (straight cut slots) they are very close tolerance too!!! nicks and burrs on the brass will jamb them up tight!
