I Have a Winchester 30.30 built between 1926 and 1932 that I can find little or no info on. It is a Model 55. I have seen pics of a standard grade, but this one is not standard, it has a pistol type grip stock, Winchester medalion on bottom, metal butt plate, fancy grade walnut, checkered fore stock and shoulder stock and is also a break down model. Can anyone shed some light on this? The museum says that files for that time were lost in a fire at some point
