22 RF Gallery George DeVogelaere


I was given several 22 RF gallery cartridges. With them was a hand written note “.22 Gallery Geo. DeVogelaere Rochester, NY”.
There were two different headstamps “H” and the CCI “target” headstamp. They appear to me to be nothing more than 22 new primed empty cases with .22 cal Crossman type air rifle pellets. Who is George DeVogelaere? The only reference I can find have to do with bullet traps and air guns. Does anyone know anything about these cartridges?

Thanks Paul
