Need Info on Bruno .22 single shot

I am not if this is what the gun is or not but the index card I got with it calls this gun a Bruno. It is a single shot .22 with a 22" round barrel and no sights. The top of the reciever is grooved for .22 tip-off rings. The right side of the reciever says D000144X and with it out of the stock, on the right side of trigger it has overtravel adjustment stamped on it with an arrow pointing to the screw. On the left side of the reciever it says Made In Australia. This is the only markings on this gun. If anyone knows about this one or value, please reply. I can provide pictures if needed.
Thanks
