To determine the age of a Remington Model Sportsman with the serial number 773769, you would typically refer to Remington's serial number lookup resources or historical production records. The Model Sportsman was produced from 1939 to 1962, so the serial number indicates that it was likely manufactured in the early 1950s. For an exact year, consulting a detailed Remington reference guide or contacting Remington directly would provide the most accurate information.
Do not see a 543 in any of my references. Sorry-Sportsman is associated with the Remington centerfire rifles in Model 76, 760, and model 78.
There is no model number 3006 or 243 in the Woodmaster line. Check Remington's webiste under the Sportsman's Library.
1930-1947
Should be on the action, Sportsman could be the 48 or 58 semi auto. Sportsman models have little parts left so try not to break any.
