Guys, thanks for the info; I can only wonder how long this sat considering all the other stuff they collected was safely stashed or stored.
Here are a few more clear pics...
Wadding at the bottom of the box, these were the last that were in one piece. 9/16"dia. What is between the paper discs? Cork? Most has turned to powder.
A 12ga trap load fit, but the tool says 10, assume 10ga.
The tool is stamped with what appears to be
PAT AIR L CIH 107
Please let me know what is really says, if you know...
