if you look down on the luger top you will see a date. that is when it was made.....
It is impossible to value a Luger with just a serial number.
on top of the luger, where the barrel goes into the receiver ther is (usuaally) a date. On the left side of the frame, just down from the date is the serial number. Usually not more then 4 numbers
The age of German luger serial number 65 can vary depending on the specific model and year it was manufactured. Generally, lugers were produced primarily in the early to mid-20th century, so if the serial number refers to a historical model, it could be over 100 years old. For an exact age, one would need to reference specific historical records related to that serial number.
value depends on overall condition
look on top of pistol, just behind ejection port and you will see date it was made
the frame
Try asking at Jan C. Still's luger forum.
look on top of gun, just where barrel is attached to receiver, you will see four numbers. that is the date made
You must seek the services of a qualified appraiser.
They were originally made in 7.65mm Luger (.30 Luger) but many were rebarreled to 9mm Parabellum (9mm Luger). Have a gunsmith check it.
Most Lugers had the four digit serial number, and they were repeated on a monthly cycle... it's not uncommon for up to 400 Lugers to have the same serial number. An actual date of manufacture should be printed on the top of the receiver, in the area where the barrel connects to the receiver.
Way to many variables and a scant description. Go to Jan C. Still's Luger Forum and look around.
