If it is a German Lugar then: The information won't come from the serial number. Look at the top of the pistol's barrel as it is pointed away from you. Look at the end closest to you. Do you see a letter, or a four digit number or a two digit number? If you see a 'G' this means it was made in 1935. If it is a "K" then it was made in 1936. If you see a four digit number, then that is the year it was made. If you see a two-digit number, then it was made in 1941-1944, see number 41, 42 43 or 44, to identify the year. Hope this helps. Checkout web sites, there are experts available on German weapons.
It is impossible to value a Luger with just a serial number.
if you look down on the luger top you will see a date. that is when it was made.....
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
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They were originally made in 7.65mm Luger (.30 Luger) but many were rebarreled to 9mm Parabellum (9mm Luger).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.
