ID Echo Shell Holder #7

[William Yanda]

I am trying to ID an Echo Shell Holder. The brand ID is confirmed by comparing to a similar item on the electronic marketplace. It is a small cylinder, with female threads and a slot in the side opposite the opening on the top. A .223 case is too large to fit, I mike the opening at 0.299.
Does anyone recognize it, or can you direct me to a chart of Echo shell holders. My Google Fu didn't work this morning.
Regards

Handloader's Digest #4 says it is for the 22-Hornet. All the old Digests (editor: Dean Grennell) had very complete shell-holder charts.
