To determine the age of a Mod E 15 Cal 22 LR FIE firearm with the serial number E844272, you would need to refer to FIE's manufacturing records or relevant databases that provide information on production dates based on serial numbers. FIE (Firearms Import and Export) was active primarily in the 1970s and 1980s, so it's likely that this firearm was manufactured during that time period. However, without specific records, I can't provide an exact year of manufacture.
FIE stands for Firearms Import & Export. Cheap guns imported from West Germany, Italy, and manufactured later in Miami, Fl. E-15 is a ruger knock-off.
