I have heard of High Standard, but the rare part is the DOUBLE action 22 revolver. You don't see many of those. Don't know that I ever have. Maybe I am not very informed as I am fairly new to handguns, but that sounds like a KEEPER to me. If it is in good working order and shows little wear, it would probably fetch $300-$400 on gunbroker.com. I have tracked a few 22 revolvers lately and that seems to be what they are going for. I am sure there must be some others here who have more info for you. Good Luck.
