If you could post a pic that would help, .. but anything printed on the barrel or action or any distinguising marks would be helpful ... also if there is a serial # don't post the whole thing ..
If the serial # were 123456 for instance just post 123XXX
Look forward to your further info so some of us may be able to give you more info.
I'm intrigued by the description of this being a side by side in 410 and 22 , you didn't mean over and under in 410 and 22 did you? Or is is a drilling set up with 2 410's side by side and a 22 either over it or under it? Just curious as I've never seen a side by side as you mention ... but I learn stuff every day
