I am a firearms collector (hobby only) from the US. I have an interesting piece. It's a Winchester Model 1873 saddle ring carbine marked with an RIC crest and marked also "W. Morton & Son Ireland"--it also has British proof marks. It was by the serial number manufactured in 1882. I have done some research to find others that are similar but have not been able to do so. I know that Morton was a gun manufacturer located on George Street in Cork, which started business in 1846. If anyone has more and better information than I do, thank you for replying.
