Guys, As I was cleaning my dads garage yesterday. I found a .22 LR rimfire revolver in one of his cabinets. I asked my mom about it and she showed me an expired photocopy license with "TELL" as the name of the unit. It has a Made in Germany marking and an imprint of what appears to be a Viking. The TELL name is inside a letter O. Tried to google it but came up with zilch. Any ideas? Thanks guys!
